If you've ever had your favorite coffee mug stolen at work, you may want to try the Plug Mug. This ceramic mug features a rubber plug that, when removed, renders the coffee cup useless. If you step away from your desk for an extended period, take the plug with you to prevent coworkers from using the mug.
The 16 oz. Plug Mug is a perfect gag gift that thwarts office thieves. It retails for $11.95 at the Neatoshop.
