Apparently a woman in South America was caught smuggling one of these, along with some Marijuana. in her hoo-ha.
There looks to me like there's an awful lot of sharp edges happening to be puttin that up my cooter. My boss has assured me that it is not likely, unless she was extremely dexterous, that she could have pulled the pin on accident, but I still can't imagine having the mindframe where I would be willing to hide a grenade in my muffin.
Just in case you're wonderin, there aint no pot up there either.
