Harsh but...
Yea ok, he stole some animation the guy used in his animation. He's jealous, and made a (slightly better) version of the animation.
Its wrong yes, but hey give the guy some credit here. He did add some original parts to the movie and its not like he just stole the whole thing and added crappy stuff.
I mean, the animation wasn't half-bad, and the laughs weren't either.
