Bonuses for Atton if you complete the game x amount of times... can't remember:
Atton [on Peragus II, after seeing the Exile in her underwear]: Are you an angel? Oh I'm just kddding. That's the worst line I've ever used -- hope some kid doesn't start using it.
The whole Korriban-tomb thingy with all your team members coming up from no where had me laughing.
Atton-Kreia arguments most definatly...
Kreia: I will be in my chambers...
Atton: (something like this) Well, I'd be in my chambers, but since I don't have any I'll just go into the c0ckpit like I normally do.
