Isn’t it Acathla in the big rock? (The Judge was in several boxes.) Which would make it either Becoming Part I or Part II.
Mindwanderer’s quote is Anya to the Scoobies, explaining the concept of alternate worlds in Superstar.
–Cliffy
P.S. On preview I see that Ezekiel beat me (hamsters!), but since he didn’t provide a quote, I posted anyway.
“I…am…pleasant”
I think this one might be in multiple episodes, but Cordy said it while looking in a mirror in the Angel Ep “The Shrowd of Rhamon” remarking on her big teeth.
And now for a quote that (if you get TNT) will be on today at 5PM Eastern Standard Time in the US)
“People who don’t care about anything will never understand the people who do.”
“Yeah, but we don’t care”
Series finale of Angel.
“Did you know the devil had a robot?”
That’s Angel to (I think) Wes in The Cautionary Tale of Numero Cinco
“Anyone else feel like the last feisty wife in Stepford?”
Thats Lorne to the crew in “Sacrifice”
“All monkeys are French. You didn’t know that?”
Oz, to Willow, before they decided to make him taciturn. Google tells me it’s in What’s my Line, Part I.
–Cliffy
Oz to Willow, What’s My Line, Part 2
And kind of an easy one, but I like it:
Just sitting here, watching our barren lives pass us by. Oh look, a cockroach.
And to answer Cliffy’s
Xander to Anya(?) in As You Were
Thats Willow to Xander in “Angel”
“How long have you known your girlfriend’s Tinkerbell?”
Xander to Willow… I forget what episode. 
Afterlife?
Don’t y’all think this is some kind of government conspiracy? Cuz my friend Levon says the government is always taking kids and experimentin’ on 'em. Did anybody else have to take a personality disorder test recently? They ask you about politics and your bowel movements and if you want to be a florist…"
Has to be Fred, she’s the only person in the Whedonverse to say Y’all. The episode is Spin the Bottle
Now for a slightly different (though equally easy) test
The following quote appears in at least 2 episodes. Name them both.
“I think I’m kinda Gay”
Willow, in Doppelgangland and Tabula Rasa
Back in a minute with another quote…
** Oh, scary vampires, they die from splinters.**
Thats Dawn in her journal in the episode “Real Me”
“Every day you wake up, it’s the same bloody question that haunts you: Is today the day I die?”
Dawn said it in Real Me
Apparently we’d be risking a tragic chain reaction, but… I just really like… coffee. I think coffee might be worth it. And I would like to get to know coffee better.
Buffy to Ben in I Was Made to Love You
err, I thought it was Ben to Buffy?
You’re right. Sorry.
He asked her out for coffee she went all emotional meltdown and that was his response. I should be mocked for my impertinence.
