This bit from KOTOR 2 was pretty funny
Atton Rand: Just so you Jedi know, the whole "cryptic routine" isn't mysterious, it's just irritating. If you really *can* see the future, you should be at the pazaak table.
Exile: But to know the future, one must know yourself.
Atton Rand: What was that, some kind of joke?
Atton Rand: That's what I'm talking about. "Jedi talk". You two should start your own little Jedi Academy.
Exile: But to teach, one must be willing to learn.
Atton Rand: All right, all right! Cut it out, I get it, I get it! The last Jedi in the galaxy, I get the comedian who runs around in his underwear.
Also, most of the things Joker says in Mass Effect.
