Homer: I'll assemble it myself!
Bart: Dad, no! Think of the bike!
Homer: I can make a bike! I made you!
Bart: Yeah, great workmanship (dislocates his arm)
Homer: Hey, that's gonna win you a lot of bar-bets some day.
Lisa: I'm keeping you! You're Snowball 5, but to save money on a new dish, we'll just call you Snowball II and pretend this whole thing never happened.
Principal Skinner: That's really a cheat, isn't it?
Lisa: I guess you're right, Principal Tanzarian.
Principal Skinner: I'll just be moving along, Lisa. Snowball II.
Homer: A 10-speed bike? What did your mother say?
Bart: She said yes.
Marge (yelling from the kitchen): I said no!
Homer: I'm confused, which is it?
Marge: It's no! His old bike is fine!
Homer: Yeah, the kitchen lady is right, your old bike still works.
Bart: Okay, I've been studying Frinks' robot and I've discovered he has one small weak spot. (sees Frinks' robot getting a spike plate installed) Uh-oh, his weak spot is now his strongest point.
Homer: (inside the robot) OOOOHHHHHH!!!
Bart: That moan sounded almost human…
Homer: (from inside the robot) THE HELL IT DID!
