I'm surprised that a large number of states allow marriages between first cousins. How do you define a half-cousin? I once read that the offspring of first cousins is only about 1% more likely to have a genetic defect than the offspring of perfect strangers.
Kentucky absolutely shocked me. I thought we were just doing baby steps since just this year our legislators decided that you can't have sex with pets. Don't worry though, if any sultry livestock catches your eye you can still take that sexy beast to Poundtown.
