The Pessimist's Mug™ has been specifically engineered by our chronically cynical friends at Despair Laboratories™ and it's the ideal gift for anyone who worships at the altar of Larry David. That's because this crystal-clear glass mug features a halfway marker underneath which the words 'This glass is now half-empty' are printed. So whenever things are looking up, one glance at the Pessimist's Mug will soon remind you that life can only get worse. Which isn't such a bad thing, because once you get used to eternal pessimism it can be just as agreeable as groundless optimism.
