A hardcore geek guy that I know recounted a little story, of how a couple of girls got him to protect them from some "creepy stalkerish guy" in the wee hours of the morning.
It was 1am (huh!), the girls were drunk (ah!) in the middle of the week (how classy!). After the stalkerish guy had moved on the geek took the girls back to their home in his car.
What a nice guy.
