Cordelia. It was in Season 1 of Angel, but I’m not 100% on the episode. I want to say one of the first handful. She had a part in a garbage bag ad. Or she was auditioning for it. I believe that may have also been the episode she suggested that the team charged people for their help.
‘My head’s gone numb.’
Doyle in Angel S1’s The Bachelor Party to one of the members of the party (the best man or the groom, I can’t remember).
Weird love’s better than no love.
Buffy to Dawn in Intervention. (Quite appropos, considering all the things the Buffybot was up to with Spike that episode!)
“I’m a breast gal myself… but then again, you knew that.”
Willow to Buffy-who’s carrying a bucket of chicken-in Life Serial (I think).
“That’ll put the marzipan in your pie-plate, Bingo!”
Buffybot to remains of Vamp in Bargaining.
I’ve been around death before. A lot. I’ve lost people. I’ve killed people.
Angel talking to Cordy, after Doyle’s passed on the visions to Coredy, in the ep where the crew saves the little boy from the demon only to discover that the boy is worse than the demon.
Oh, I got the stones. I got a whole bunch of… stones.
Buffy to Spike, “Something Blue”.
My quote:
“I think I need a lawyer!”
What is this now, the Law and Order quote game? 
By any chance do you mean “I want to see my lawyer”? Because that would be Cordelia to Angel in “You’re Welcome.”
I’ll reserve posting a new quote pending clarification.
Nope. Want a hint? It is from AtS, but season 1…
Oh! I got it. “I think I need a lawyer!” was said by Charles Gunn, in AtS “Blind Date.” Gunn’s in the lobby of Wolfram & Hart. His next words were, “I think my civil rights have been violated” or something like that.
Try this one:
Who was mentioned as a “Tall guy, bleached mullet, works day shifts?”
Machiavelli
(and FTR, that was Buffy to coworker night-school MBA guy in As You Were
“Giles help! He’s gonna scold me!”
Buffy, teasing Spike in “Something Blue”.
Here’s a tricky one:
“Yes. I am a lesbian.”
Thats Riley to Buffy in “Something Blue”
“couple of supplies here, that I think just might help. Eases the hurt, makes the sun shine a little brighter, even makes boring people seem more interesting.”
Anya to Spike in “Entropy”, shortly before Anya is upside down and halfway to happy-land.
Next:
“You will never comprehend the source of our power!”
Buffy, Willow, Xander and Giles, all being channeled through Buffy, in Primeval.
“I hate that girl!”
Then annointed one (Colin), at the end of Season 2, episode 1, When She was bad
“And if there was a God, don’t you think he’d keep it that way?”
The ep is “Reptile Boys,” wherein the frat boys are trying to sacrifice a girl to the big lizard in their basement. The speaker is Cordelia, replying to Buffy’s disinclination to meet frat boys; she’s reluctantly trying get to Buffy to agree to the party so SHE can go, herself - one of the frat boys is named Anderson and his father owns Anderson Cosmetics, apparently a world-reknowned and wealthy firm.
I don’t wanna be our only hope! I crumble under pressure! Let’s have another hope.
I think this is Willow in Chosen when faced with casting the spell to activate the Potentials.
“It’s a ritual sacrifice, with pie.”
Anya to Willow and Buffy in “Pangs.”
“It must be Tuesday.”
