Who hasn't contemplated sending away for those "male enhancement" pills offered by friendly, reliable spammers? Well, if you pick a less-than-reputable company, you might end up six feet under because of your quest to get a rise.

Authorities in Singapore are "very concerned" after a middle-aged man died after consuming an illegal sexual-enhancement pill called "Power 1 Walnut" that contains high amounts of controlled drugs. Six other men were hospitalized after popping the pill -- the country now has 23 confirmed cases of sickness from it and many more suspected. The pill contains glibenclamide -- which is used to treat diabetes -- as well as sildenafil (aka Viagra).

So when you're traveling overseas to get that kidney donation from a Chinese inmate (and maybe a little plastic surgery in a sketchy clinic/tattoo parlor in Bangkok to take care of those unsightly man-boobs), watch out for the sex drugs. Those are really dangerous.
