Ho ho ho?
DAWN: Um, guys, hello, puberty? Sorta figured out the whole no Santa thing.
ANYA: That's a myth.
DAWN: Yeah.
ANYA: No, I mean, it's a myth that it's a myth. There is a Santa Claus.
XANDER: The advantage of having a thousand-year-old girlfriend. Inside scoop.
TARA: There's a Santa Claus?
ANYA: Mm-hmm. Been around since, like, the 1500s. He wasn't always called Santa, but you know, Christmas night, flying reindeer, coming down the chimney -- all true.
DAWN: (smiles hopefully) All true?
ANYA: Well, he doesn't traditionally bring presents so much as, you know, disemboweled children, but otherwise...
TARA: The reindeer part was nice.
