"Dos horas mas tarde." "That's Spanish for 'Two Hours Later'!"
From "Doom Baby":
BABY RICHARD DICKSON!!!
At the end of that same episode:
BABY SANJAY DICKSON!!!
The Dicksons dropping Baby Dickson off with Sanjay and Craig, not because they think the duo are responsible enough to care for a child, but because he's wanted by the police and needs a place to hide.
From "Heightmare": Sanjay and Craig realize they don't need to impress anyone by going on a dangerous roller coaster and try to leave, but the seat restraints come down and lock them in. Sanjay asks the carny to let him and Craig out because Craig allegedly has a heart condition. The carny's response: "Oh, I'm sorry. You must have mistaken me for a guy who gives a crud."
Huggle Bunny, especially his stage show "Huggle Bunny: Gettin' Money" at the carnival.
Even better is his appearance in Boatin' Down the River, where Sanjay and co. are floating down a mattress, and they meet different people. Each time making snide comments. But when they get to Huggle Bunny, they are all completely silent.
