People in Sunnydale have to be deeply delusional to live there. I think it rubs off in their baby names. [and that's a big grin.] Willow's mom is very hippy-ish. Xander's name is actually Alexander and Spike was William before he started--a story that isn't appropriate company material. Anyway, he wasn't born Spike and Giles is British.

[Because that explains everything.]
