Ok, figured I would update this already extensive list of quotes
season four ep "The House Always Wins"
Fred: (re: Vegas) Yeah, but the reason we're here is to see Lorne, right?
Angel: Absolutely. Maybe afterwards we can check out that Danny Gans guy I keep seeing billboards for.
Angel: Wow! This place sure has changed.
Gunn: Get out! You never told me you'd been to Vegas before.
Angel: Yeah, a few times. It's been a while though. Used to be dunes over there.
Gunn: Oh man, it has been a while. They tore down The Dunes 10 years ago.
Angel: (snickers) Not the casino. I meant actual dunes.
Gunn: (re: Lorne) No one seems to be bothered by the fact that he's a demon.
Fred: They must think it's all make-up. Uh, like the Blue Man group. (pauses) You don't think the Blue Man group...
Angel: Only 2 of them.
Angel: (re: the Tropicana) This place was so much friendlier when the mob ran it.
Gunn: (outside Lorne's door) Man, heads of state don't get this much security. Something�s starting to look a lot not right about this.
Fred: That's what I've been saying, only with better grammar.
DeMarco: How did you win on that slot machine?
Angel: I put the quarter in the slot, and I pulled that little lever.
DeMarco: Are you playing games with me, vampire?
Angel: I have to play to win.
Angel: Oh, now I remember that room. Elvis and Priscilla's wedding reception, 1967! Yes, all right. It's not like I was, you know, really invited. They just put me near the dais. I think somebody thought I was in the band. Possibly because I was all drunk and surly. (chuckles)
