Are you tired of coworkers taking your personal coffee mug? You can’t identify who is doing this? Here is a more or less subtle way to tell them what you think about their act. Up Yours Mug features a certain finger being flipped at the person who “borrowed” your mug. If this doesn’t make them stop then nothing will. but the finger is also shown when you drink your coffee, you say? Yes, this is a reminder that life sucks sometimes. It is a perfect for Monday mornings. On the positive side, when the life gives you the finger, at least it also gives you the coffee.
