Not that funny, but still good...
The problem is, there isn't any build up. If I didn't read the comments I wouldn't have known that Mr. Information is a know-it-all. So it seemed just like some guy smashing a child's truck (which it actually still is.) In just 5 or so seconds, you could see an other kid leaving after getting a really smart answer, IMHO that would increase the joke.
Besides that, the animation and the style you used were of great quality, I don't have anything to note on that :)
Keep on making stuff ^^
