Mr. Burns: (to Homer) Could you explain your model, young man?
Grimes: (from audience) What's to explain? He's an idiot!
Lenny: Pipe down!
Homer: Well basically, I just copied the plant we have now.
Mr. Burns: Hmmm.
Homer: Then, I added some fins to lower wind resistance. And this racing stripe here I feel is pretty sharp.
Mr. Burns: Agreed. First prize. (gives Homer a blue ribbon)
Grimes: What?!
Carl: Way to go, Homer!
Lenny: You're number one, Homer!
Grimes: But it, it was a contest for children!!
Lenny: Yeah! And Homer beat their brains out!
