Dirty Glasses: "Moist and Merry"

The "Moist and Merry" drinking glass collection by the aptly named German design company
Donkey Products. Unfortunately this collection is no longer for sale on their site, but you can check out other quirky items in their shop, which is like a cross between Spencer's Gifts and Fitzsu with Presidential tea bags, nipple doorbells and crocheted power tools. Leave it to the Germans to create a crass, yet clean and appealing product design--despite the fact that it insinuates you're drinking pee.

Some other non-pee designs:
Dentures Glass
Little Red Riding Hood Glass, designed exclusively for Brigitte Magazine(wolf gets bigger when water is inside)
