Studying to be a proctologist? Just want to practice for your own impending exam? No problem. The USB Endoscope has got your back…side…all scared and puckered up. This two-foot-long USB-powered roto-rooter snake has LEDs and a camera at one end, as well as a powerful 40X microscopic lens. Nasty applications aside, it could be pretty useful for getting into tight spots, having a look in ancient tombs or whatever. I’m not sure it’s worth the $140 price tag, but if you buy one and complain, you know where you can stick it.
