When your brain explodes out your other ear, you don't want to be getting any in your eyes. Also, its not a plug, it just ties them to the table so you don't steal them.
I have a special syringe for this. I had impacted ear wax a few years ago and I went to urgent care to get it rinsed. Turns out my other ear was also impacted, just not as bad. After the rinse, I could hear in 3D. I felt like I shouldn't have been allowed to drive home because it felt like I was on acid it was so overwhelming. On the drive home I heard a crappy Honda with a bad exhaust drive by and I was scream-laughing at how visceral it was.
Now I rinse regularly in the shower and don't get to have free acid trips :(
