Well... It's too long for that babykiller joke. Just like the "You lie!" and the "You're a jerk!" jokes, it's just done over and over... It's like hitting a guy with a baseball bat, first time you laugh, second time you chuckle and third time you yawn. It would be a bit of the same if Arnold Schwarzenegger said "hasta la vista, baby" every time he owns someone.
I like the style of animation though, so it ain't all that bad, you just need to know when a joke have gone too far.
