Pink. Rubber. Duck. Vibrator.

Not only is this rubber duck pink—or "Paris", as they call it—it runs on only two AA batteries. You activate the duck by pressing his torso, which makes him bzzzz bzzzz bzzzz you into tranquility. If you happen to share a bathroom with roommates, or god forbid your parents, this is a good way to disguise your playtime toy.

As an added bonus, there's a travel version that's half the normal size and runs on one AAA battery. Although not quite small enough to go properly spelunking, it still provided us could provide you with hours of enjoyment in your hotel room at CES.
