What's something weird and mostly useless that you can do with your body?

I can wiggle my ears. I used to use it to entertain children, but today's children are jaded and cynical.

I can rumble my eardrums. Mostly useless unless i wanna block out some annoying sound but i can only do it for like a minute at a time.

This is my time to shine, my body is full of useless, I can:

• gleek intentionally (saving people a search: it’s causing the salivary glands under your tongue to shoot saliva, people often do it unintentionally when yawning)
• open my jaw wide enough that it goes out of socket, and twofer I can then move it side to side and produce a loud popping noise
• bend my thumb down to my wrist
• cause my heart rate to spike for short periods even when at rest
• make a three leaf clover with my tongue
• click my tongue extremely loudly

I can hum and whistle at the same time. Makes me sound kinda like a Theremin

You know that feeling you get when you listen to really awesome music and your hair stands on end and your skin has like an electric tingle all the way up and down? I can do that feeling at will. It's called 'voluntary frisson', normally an autonomic response. Makes music a real.trip.

I just remembered this, I can open my eyelids and look in a direction where only the whites of my eyes are visible. Apparently it's very creepy

I can make my left elbow sound like biting down on dry cornflakes, just by doing a push-up.

I can twitch my eyeballs left and right really fast, and not just a little bit - but most of the way.

Completely grosses people out when I do it.

Edit: I can even do circles, but not as fast as left and right.

I can voluntarily open my eustachian tubes and hold them open, without needing to yawn or swallow. Makes it much easier to clear the pressure in my ears when changing elevation (like when flying in a plane).

Lots of things that ultimately come down to hyper-mobility (thanks Ehlers-Danlos!), including:

• Lick my elbow
• Pull my shoulder visibly out of socket (not painful at all, and happens if I carry something heavy if I’m not careful)
• Pop my hip out of socket while standing (sometimes painful, always somewhat unpleasant, so I’ve had to learn how to not do it)
• Hold my hands behind my back and pull them to my front
• Rotate my arm >360°
• Bend my thumb to my forearm

Apparently there's a thing called lucid dreaming that many people try very hard to achieve.

Most of my dreams are "lucid".

I can also, using only my facial muscles, pull my eyelids back extra far so it looks like my eyeballs are popping out.

I can dislocate my shoulder to the music of Billy Joel. The Pawnee Journal once called it, "Why would anyone do this?”

Exist.

I can flex some muscle in my head that causes a roaring sound in my ears. Not sure what that's for.

There is a tiny hole in the roof of my mouth that i can suck air through.

I can hammer nails and icepicks into my head. I'm very fire resistant and eat fire. I have a split tongue. I can keep my eyes open for a VERY long time.

TBF I'm a sideshow and fire performer so I'm cheating

I can whistle from my throat, I figured out how to do it from yawning and just kept practicing, the wife hates it because it hurts her ears but every time I yawn I have a habit of trying

I can poop on the floor. But I bet you can too.

I can whistle in three different ways. The classic pursed lip whistle, a whistle using just the tip of my tongue and the roof of my mouth, not using my lips at all, and then another using the tops of my bottom teeth. I can make decent bird sounds using my bottom teeth, but I can do pretty much any tune I can think of with the pursed lip method. It has been relevant to my life exactly zero times, except to entertain myself.

I can whistle while either exhaling or inhaling

Idk how special or weird it is but everyone I've tried to teach the skill to seems entirely incapable of doing the inhale one

It's super useful for whistling complex songs or long bits without stopping, though

I can inhale through my butthole to fart on command.

Sooo I can cause what honestly feels like a small and constant electrical current flow through any part of my body. If I center this feeling on my chest it is easily more prominent than anywhere else with my head being second. Extremities are dead last. If I am hooked up to a heart monitor I can make it freak out at will. Any location I focus it on tends to want to tense up.

I like to tell people this is the result of me grabbing onto a metal item when I was younger that was still hot. Couldn't let go for a solid 6-10 seconds, can't say exactly how long. What I am able to do feels very similar.

I can roll my R's like a Spaniard and move my boobs on their own but that's it.

If I press on the corners of my eye it forces air down my naso-lacrimal duct (that lets tears drain into our sinuses) and it makes a squeak loud enough for people sitting next to be to hear. I have a built in nose flute.

Well, I can still do a cartwheel, it's good for surprising children. Thumbs bend backwards.

I can also reach all of me, which my husband seems to think odd, can put sunscreen on my own back so I don't think it's useless.

I can fit the majority of my little finger up my nostrils. My nose might be slightly larger than normal and my hands are about normal. It just fits up there with a little twist.

I can rotate one finger at one direction and the other on the opposite direction while pointing one to another, simultaneously. I don't know how uncommon it is but, back at high school, no one else in my class could do it. Totally unuseful skill.

I can crack the knuckles of my big toes at will (only moving my toes, no hands involved).

Due to an NDA I signed, I am unable to answer your inquiry. Next question please.

I can put both my hands In a "pray" position behind my back between my shoulder blades. I can vibrate my eyes. Perpetually crack my right ankle. And pull my arm out of it's socket.

Fall asleep standing

Wake up and go about my day.

I can move my fingertip joints without moving the rest of my finger.

I can trigger a few seconds vertigo attack when I lie down. If I do not think about it when going to bed, everything is fine. But if I think about it, then it invariably comes.

I can

• Bend my fingers back almost to the back of my hand, effortlessly
• Raise/lower my eyebrows by a lot, even independently. I can make waving motions, as well!
• Touch the tip of my nose or chin with my tongue
• Wiggle my ears (though not independently)
• Roll my eyes up so only the whites at the bottom are visible

I can snap with my toes the same way people snap their fingers, but only with the right foot for some reason.

I can make fart sounds with only my hands

I can spiral my tongue, so that the front part is fully upsidr down - but only to the left. I can't rotate it to the right at all for some reason, it's like the equivalent muscles are missing.

I can throat sing but it's not completely useless

The best way I can describe it is I can make the nerves on the back of my neck, upper back, and shoulders feel sensitive at will.

Blow bubbles off of my tongue

I can make fart sounds by squeezing my palms together

I can bring my hands from the back of my body to the front (and the opposite) while holding them together. There might be a use for this if I ever get tied up.

I can hear the blood flowing in my head, including hearing my own pulse via the same sound.

I can cock both eyebrows one at a time

I can touch my palms flat to the ground while trying to touch my toes

I can bend the last joint in my fingers independently. I also have a small nub on the tip of my tongue, which is only useful in one situation.

Sit in a cubicle for 8 hours a day.

Talking.

I can bend my knees backwards by, like, 20°.

I can make my right arm vibrate by tensing up the muscles in my forearm. I dont me shake really fast. I mean vibrate.like, fast.

Outside of beating my brothers on specific mario party mini games that require repeatedly pressing a single button (or other games that have that use mechanic) or unlocking the cheats in bomberman 64 (needed a turbo controller to hit start repeatedly on the main menu) its pretty damn useless.

There was one Mario Party mini game (i think called domination) where you had to hit A as fast as possible, with each press making a thwomp or "domino" appear in a line. At the end, they all fall down, and you see whose line is the longest.

Some people couldn't reach the finish line. Some could just about get past it. Mine just kept going and going.

Otherwise, totally useless.

I can sing really poorly.

I can fold my ears twice - so from the top of my ear I fold it towards the bottom of my ear and at the point where it folds I can fold it again across over the first fold.

Not a thing I can, but I once knew a person who could make their eyes go anti-crosseyed, as in left eye looking far left, right eye looking far right, away from their nose.

We have a couple things that run in the family. All men in my direct family (so me, my dad and my brother) can twist our mouths in both directions at once, so upper lip one side lower lip the other side, looks funky. We can also do eyebrow dances with moving only single eyebrows but I think that's more common.

I can diverge my eyes really far, almost equivalent to how far I can cross them. Way easier when I'm super sleepy.

I can usually make my goosebumps on my arm go away by concentrating alone.

My left pinkie finger knuckle can hold some tension when I from my pinkie into a claw shape, but then snaps forward. Either that's unusual or my right hand can't do that as snappy.

I have a few that some others in the thread have already mentioned, but I can also:

• wiggle most of my scalp back and forth
• retract the middle of the tip of my tongue so when I stick it out, it looks like an ass
• stop peeing mid-stream. Maybe this is perfectly common, but people talk about not being able to just stop, or at least not for longer than a few seconds.

I can snap the tendon over my knuckles kinda hard to where it makes a popping/snapping sound. If I do it close to someone's cheek, it stings like releasing a tiny rubber band.

I can also move my ears independent of one another.

Pop my knees
