First Place: Winter Angel

Buffy: I told you. Never feed them after midnight, and do not get them wet. But would you listen? Noooo! Didn't you ever see the movie Gremlins?
Angel: Yeah, but how was I to know that Furbies did the same thing?
Spike: Bloody idiot! Everybody knows that!!

Tied for Second Place:

Angel: I told you two that Dru would be upset when she found out about our menage'a'trois.
~Andra

Be very, very, quiet. We're huntin Whedons!

Angel: You're right, Buffy, he _is_ a demon.
Buffy: See? Told ya.
Spike: Bloody 'ell, will you just stake this Ricky Martin wanker already?

~Jason

Buffy: "Dammit, you guys! I *told* you not to wear leather! Now the cows are after us again! And I am *not* milking them all this time."
Angel: "But leather looks good with my complexion..."
Spike: "Look, mate, we all know you're color blind. Now you deal with those SPOCC blokes, I'll get the buckets."

~Jane, the Frog on the Wall

Special Mention, because they appealed to my ego:

Buffy: Told ya so.
