Sick of people using or stealing your coffee mug at the office? Well, nobody will want to touch this cool new Dirty Mug ($10). This ingenious ceramic cup may look like it's covered in coffee stains and in need of a good scrubbing, but it's actually just a clever disguise. The only downside is that although you know the cup is really clean, everyone else will now think you're a slob. (via Michael Kiely)

This is basically what all my mugs look like anyways, so I might as well just buy them looking like this. (via urbanoutfitters.com)

Right girls what do you think to these, I am not sure I could drink out of them as they would never look clean but the idea is fun and different which is refreshing to see!

Coffee stains? Lipstick smudges? What a Dirty Mug! Ceramic coffee mug is purposely and strategically "dirtied" for your enjoyment.

One of the cutest effin' coffee mugs I have ever seen... shabby chic. I love coffee.

i think if i actually got this, it might trick my husband into thinking that all of my dirty dishes are actually 'clean'.... if only to postpone the enevitable (sp) dishwashing for a bit... it probably wont work, but i think its a great idea :D

Drinking out of a real dirty mug, well, that's just gross. But, a fake one? Now, that's just funny.
