All right, I'm cheating because I looked these up, and I'm sorry if I repeat someone in a previous post, but there is officially enough activity in this thread to make it hard for me to keep track. So!
Evidentially, in Alabama, it is illegal to play dominoes on Sunday. Probably something to with God's wrath on he who matched up dot-covered tabs or something. It is also illegal to maim one's self to escape 'duty,' which I can only assume was mostly kept in mind during the drafts of Vietnam, considering how many did all they could to keep out of being conscripted. It's illegal to wear a mask in public, putting salt on a railroad track can be punishable by death, and you can't wear a fake moustache that causes laughter in church.
Oh, it's also illegal to keep an icecream in your back pocket. Sorry, Calvin. Men may not spit on the opposite sex, and in Jasper, men can't beat women with a stick 'larger than the diameter of their thumb,' thus suggesting a suitably thin stick, or thinner, is permitted. You can't sell peanuts after sundown in one region, and bear wrestling matches are prohibited.
Biggest thing? Incestuous marriage is LEGAL. xD
