My last and only STD was back in 1970, crabs. Crabs were pretty endemic in the San Francisco area. It was a bit of an ordeal to get rid of them though: take a shower and coat yourself with this crab shampoo all over, don't rinse it off, and leave the shampoo on for a full 24 hours. Ok, but then clean all your clothes, boil your sheets, etc. I remember the crabs especially because I'd just started a new job, was sitting around the training table for new workers, and I noticed a leetle crab (the things are tiny) walking across the table. It had dropped off my arm and was headed right for a large black woman that I didn't get along with. They're happy little colonizers and not prejudiced at all.
