I live in Africa. Do I win?
Let's see: In India I ate at this great restaurant called Moti Mahal, that was about 3 blocks from my house. Every time, and I mean every time, I ate there I got Delhi-belly (aka giardia). But the food was so damn good, it got to the point that I would go to the doctor before hand if I knew I was going to eat there.
In Uganda I ate a meal at our cafeteria, and managed to come down with giardia and amoebas at the same time. Flagyl is nasty ass medicine. Anybody every take that stuff? yuck.
