According to knowyourmeme, this is a photo from a 2018 session of Japanese Parliament. The guy in the center is calling for a vote on a controversial bill, and a bunch of opposition party members are attempting to physically prevent him from doing so. Apparently this is a thing they do in the Japanese Parliament sometimes?
All good! "Fell" is the past tense of "fall". Aternatively in some cases you could say "did fall", though in modern English that's usually used as an affirmative to a question about the fallen status of the chocolate (e.g. [which is short for the Latin "exemplia gratia" , meaning "for example"], Question: "Did the chocolate fall?" Answer: "Yes, the chocolate did fall" or "Yes, it did fall").
There are actually other (irrelevant) meanings of the word "fell"; as an adjective in "a fell beast" for example, "fell" means "fierce, cruel, terrible, or dreadful"; or as a verb meaning "to knock, strike, shoot, or cut down; cause to fall" for example " to fell a moose" or "to fell a tree."
We came home one evening and discovered our 10lb wiener-pinscher had eaten a whole dish of Dove dark Chocolates while we were away. Easily a couple of dozen pieces... All that was left were little bits of foil wrappers all over the floor where he attempted to peel each one open. I'da really liked to have seen how he was doing that. We just knew he was fixin' to die. Aside from looking guilty as hell, he showed zero signs of any ill effects. There's no telling how much of the foil wrappers he ate either...
A westie mix I had once ate 9 Reese's Peanut Butter Cups. I called the vet, and they told me to give her 10cc of peroxide every 15 minutes until she vomited.
After doing so for 90 minutes, I called them again, and they told me to stop, and that she'd probably be fine, which she was.
