Alien Cathouse!
As if you really needed to hire a geek prostitute, you could always go to the Alien Cathouse in Nevada. Marvel at their 1997-era graphics! Amaze at their purple blow-up dolls and heavily-tattooed sex workers! Actually, that last one sounds pretty awesome. I'm not entirely sure what the 'alien experience' is there, the website makes it look sorta like a nice, clean brothel (which is a plus, of course), but I'd like to see more 'alien' in their entertainment selections.
