Anti-Theft Coffee Cup

Tired of having your coworkers mysteriously using your coffee cup? Who knows where their mouths have been? The Anti-Theft Cup solution is delightfully useless and utter genius as the same time. The cup comes with a hole in the side that strategically makes whatever liquid your coworker deems worthy of slurping down undrinkable.
The only way to make the cup drinking friendly is to insert the specially sized key lock which plugs up the security hole (hehe puns). Plugging up the anti-theft feature. One thing we wonder about is whether the Anti-Theft Cup is leak-proof. That could be a sticky situation. — Andrew Dobrow







there’s something dirty about plugging the hole in a cup with a stopper that’s been in your pocket on a keychain all day.
That’s absolute genius. And as for the dirtiness, it’s just as clean as if you were to clean the cup itself. The stopper looks like it’s the size of a marble, hardly a difficult thing to keep clean, eh?
