On my honeymoon in Cancun I had chicken tamales that I found out later they wash the husks off in the a river or a lake. I got severe diarrhea and my luggage smelled like diarrhea for 10 years after that (probably should of just thrown the luggage away).

So then I ended up parasailing and riding ATV's and scuba diving all with diarrhea... I don't even need to explain why that was awful.
