There are a million video sites and a million humorous frat boy videos. This one makes me laugh for it's genuine nature, it's depth of character and the fact that nobody died/broke anything or otherwise ended up worse off.
We've all done it, and the laughing on the soundtrack is what makes this. Back tot he golden age of innocence in virals, funny for funnies sake.
