The Pessimist's Half Empty Mug, Glass and Shot Glass

I've certainly been told that I have a pessimistic view of the world and maybe that's why I'm getting a real kick out of The Pessimist's Mug, Glass and Shot Glass from Despair, Inc.
These glasses will always tell you when your mug has hit the half full mark.
Depressing? Maybe a little. Funny? Oh, yes!
