Claire: 15 years of training has prepared me to help these people.
Trevor: And being the Roman god of love for 3000 years had prepared me for what. Desk job at Hallmark?
Trevor: Make a move! Get in the game! You gonna get hurt? Have a beautiful train wreck.
Trevor: You ever watch Fame? You know what I have in common with Bruno, Leroy and Coco? I'm going to live forever. What about you? You going to live forever? See, it would saturate my pleasure gland to rip your skin off and make ponchos for the kids. So keep your paws off my shrink here, because I'm a frustrated taxidermist and I'd love to go deep on you. We on the same team, butter bean?
Claire: I've got all night.
Trevor: Tremendous. I'm free too. Maybe we should hang the "do not disturb" sign.
Woman #2: What?
Young Man: Why?
Nick: He's gay!
Group: (getting it) Oh.
Mike: Gay gay gay!
Claire: At least that's been my experience.
Woman #1: I mean a guys gotta be pretty hopped up on testosterone to hit on you in a grocery store.
Mike: Wait a minute, wait a minute. I read in Dr. Allen's column that grocery stores are a safe place to encounter relationship material.
Claire: What I said regarding grocery stores was this: they afford you the opportunity to subtly note commonalities, okay. Say you're vegan and he's toting half a pound of veal, cross him off. If he's holding a pint of humus, Italian mineral water and a bouquet of gladiolas, cross him off.
