Principal Skinner : We're not coming down until you acknowledge and celebrate our love!

Maude Flanders : Excuse me, Edna. I don't think we're talking about love here. We are talking about S-E-X in front of the C-H-I-L-D-R-E-N!

Krusty the Clown : Sex Cauldron? I thought they closed that place down!
Homer Simpson : Bart's teacher's name is Krabappel? I've been calling her Crandall!
Sideshow Mel : [dressed as a caveman with a bone through his green hair] My opinions are as valid as the next man's!
