Earlier in the episode, as Alvin suddenly limps towards the courthouse.
Simon: What's with the limp? Alvin: Just a liiiiittle insurance. Simon: What happened to "truth, justice, and the American way"? Alvin: This is the American way.
In one episode where Alvin was learning to ski, but ignoring Simon's instructions, he ends up tumbling down and creating a giant snowball, which is heading toward Simon and Theodore:
(Theodore runs around in a panic) Simon:(just stands there) Why can't he just listen for once?
The Running Gag with T-shirts the episode where Alvin and Simon help Theodore on his history test. The first is when Columbus (Alvin) arrived. Later the pilgrims came and offered T-shirts to the two indians already wearing the shirts Columbus gave them.
Then in Custard's Last Stand.
Alvin as Custard: How about some T-shirts, chief? Simon as Sitting Bull: No more stupid T-shirts! Alvin as Custard: Okay. Then how about some party favors? Whoopie Cushions? Simon as Sitting Bull: Let's charge him! Alvin as Custard: No problem. I take credit cards. Simon as Sitting Bull: No! We charge you!
From the episode "Snow Wrong":
Brittany: Nobody, but nobody calls my sister a jerk!!! Jeanette: Uh... but, you do all the time... Brittany:That's different!
From "Thinking Cap Trap":
Host: Alvin, what is syntax? Alvin: Syntax...A tax the church collects from sinners?
