If the situation is bad enough, and the privileges are good enough (*cough* Indecent Proposal), I'd probably even have to consider manwhoring myself out. ;)
This is a really interesting question. It's taken a lot of strength for me to 'come out' to my uber religious friends and family, and the reactions haven't been incredibly good. However, as bad as it may sound, I think I'd fake being a believer just to get the additional benefits of claiming a religion. Being in closed spaces isn't my idea of a great time for extended periods!
