From The A.V. Club:

AVC: Because it's a kids' show, it seems like there'd be a lot of restrictions. When it comes to "protecting the children," people lose their minds.

TK: People do lose their minds with kids. Also, [they] don't give children, who are really smart and funny and whimsical naturally, credit for being able to tell cartoon comedic behavior for what it is, whether it's a kick in the butt or a funny pimp-slap to the face. When they do these studies, "By the time they're 6, children see over 30,000 violent acts on television." They're counting Elmer Fudd chasing Bugs Bunny around as if it was Reservoir Dogs. No, that's apples and oranges.
