TV Quote from The Simpsons 11x03: Guess Who's Coming to Criticize Dinner?

Milhouse: Hey, I know how we can have some fun. I spy, with my little eye, something beginning with "D."
Nelson: Dingus! [punches Milhouse on the head]
Homer: God bless you, Nelson Muntz.
Nelson: Eh, I'm no hero. I just like to hit people on the head.
