 * This exchange from Hell for the Holidays:

"Mr. Calametti: Manbird is the most difficult and least popular language on the planet. There's over 500 variations of this phrase alone. Say it loud. Say it proud. Mark: (Hesitantly) Sssuck my balls. (Mr. Calametti slaps him) Ah! Mr. Calametti: You just called my father a coward! Mark: (Cheerily) Suck my... balls! Mr. Calametti: Now you're asking for salad."
 * "Mrs. Boneraper, Twayne hurt himself!"
 * Mark learning how to speak Manbird.

"Mr. Calametti: You threw him off the roof!? I thought you were a social worker!
 * And later...

Mark: He looked ready! Clearly... he wasn't."

"Twayne: This is gonna be reeeeal freaky."
 * "Sara. No."

 * Mack Maggotbone's advice to Twayne in "Callie and Her Sister", to simply "think of something you like" when having public sex with her.

"Leonard: I can see your whole shlong from down here. Mark: Then you die a lucky man."
 * And from the same episode... poor, traumatized Doug, having to see Callie's parents reunite in a way that made even Callie cringe!
 * After Leonard and Spell-sick Mark joust when Mark stands over Leonard this exchange occurs.
