This was the discussion question for the week on my Whedonverse mailing list, but I figured that good Buffy lines are good for sharing all over the ‘net!
Xander: Do you know what’s a good day to break up with somebody? Any day besides Valentine’s Day! I mean, what, were you running low on dramatic irony? (Bewitched, Bothered, and Bewildered.)
Willow: And I’m eating this banana. Lunchtime be damned! (Dopplegangland)
Giles: Now, if we can stay in focus, keep our heads, and if Willow can stop stepping on everyone’s cues, I know this’ll be the best production of “Death of a Salesman” we’ve ever done. (Primeval)
Buffy: I loved [Angel] so much. But I knew … what was right. I don’t have that any more. I don’t understand. I don’t know how to live in this world if these are the choices. If everything just gets stripped away. I don’t see the point. I just wish that… I just wish my mom was here. (The Gift)
Spike: Oh, listen to Mary Poppins. He’s got his crust all stiff and upper with that nancy-boy accent. You Englishmen are always so… Bloody hell! Sodding, blimey, shagging, knickers, bollocks, oh God! I’m English! (Tabula Rasa)
Xander: If you have to go to the bathroom, it’s to your left. If you don’t have to go to the bathroom, picture what you’re about to face. Better to go now. (Chosen)
Do you have a favorite line from the show?
