Zomebies, robots, seriously, this mug is awesome and I want one.

From Thinkgeek:

This mug imagines a world overrun by zombies… and robots. When empty, this is a plain, ol’ innocent lil’ mug with zombies all over it clamoring for brains. But add hot liquid to it, and a robot uprising occurs! Are they here to take down the zombies? Or to destroy all humans? Only time will tell. Probably best if you keep an eye on your mug, though.
