"Hello everyone hiding, I already know a big surprise party is planned and normally I pretend to be surprised, but I'm not so sure the whole jumping and yelling bit should be done at these exact coordinates, if you catch my drift."
"But I wanted to yell surprise!" Buffy whined.
Xander chuckled. "I think Sunnydale provides enough things jumping out and scaring us don't you?" he countered.
"But it's never me doing it," Buffy complained, giving him the puppy dog eye treatment.
"Fine, tonight while we prowl around we'll jump out and yell surprise at all the vamps," Xander said.
"We can wear our party hats and blow noisemakers," Willow said, getting into the swing of things.
"Imagine the looks on their faces," Xander said with an evil grin that Buffy mirrored.
"Happy Birthday Xander," Giles said abruptly. "I wish I could stay, but I have the sudden urge to beat my head against a wall, so I believe I shall call it a day."
