Zaku-sensei YTMND is now kinda hard to watch, but years ago it when it was still fresh it was more like this. cute little sound/gif combos you could watch to get a chuckle out of. I liked all of these at least a little, and that should always be enough for stars.
Hooker I think most people know Chacarron from the Batman YTMND.
memedumpster Most of these are just Stone Cold Steve Awful, but the five or so that aren't made my day.
