If you get hit, it's your own fault.
Adam Rifkin stashed this in Simpsons!
Lisa's kicking animation pales in comparison to Bart's windmill arms (AAAUAAAUAAAUAAAU). I'll always believe that Fry's killbot arms in Futurama were a reference to that (REEERRREEERRREEERRR).
Oh god, the details in Homer's part. The air-eating animation, and the dent.
