Probably something like Sexy Girl or maybe a couple of the Playboy pins.
The only reason for that is that I’ve got younger kids. Not to mention all I need is one of their friends coming over and saying something to their parents like “I saw naked girls over at their house”. At that point I think you become the creepy parent at school.

Other than that, themes don’t bother me too much. I think games like Congo, No Fear, No Good Gophers etc are awesome games, even though I think the themes suck.
If I had my choice of themes, it would be Rock and Roll, Monsters and Sci-fi.
