For the colleague: Grenade Mug

On the other end of the floor sits the loyal soldier who delivers your packages with a smile, and he's the one you have to find a present for – thanks to your office's Secret Santa holiday gift exchange. But when you think about it, all you really know about him is that he looks like an extra on 'The Walking Dead' when he hasn't gotten his morning caffeine. And that he loves demonstrating karate. Thankfully, this cool, monotone (but nonthreatening!) coffee mug will impress the whole office without scaring secretaries or meriting a call to security. It's even microwavable – as long as he pulls the metal pin first, naturally. [$22; mollaspace.com]
