I've got only one at the moment, and it just came to me, while watching Star Trek, The Next Generation. Wouldn't it be strange if they actually had developed devices that could heal wound easily and instantly? I ould only see bad things coming from this, especially from a medical college... Imagine, just for a second, that you and your buddies get drunk and somebody passes out on the couch. Now note that in these facilities there would be said wound healing devices. Anyways, as a practical joke, theoretically you could focus the device onto somebodies asshole, dick, or vagina, and seal it shut. Wouldn't that be a bitch? Damn I sure hope that idea doesn't come to fruitation.
