How did Spike bleach his hair? I have a lot of trouble putting on my eye makeup or coloring my hair even with a mirror; I can't imagine that someone without a girlfriend to do it for him would have much luck.
I've always thought there was some back alley barbershop or hair salon (run by one of Willy's relatives) servicing the more vain demons in Sunnydale, and that Spike would be a regular customer.

I just love your funny and probing analysis, btw :-)
