The first few sips from this innocent looking porcelain mug are pretty tame, but as you continue drinking things get a lot more exciting. What's that lurking in the murky depths of your morning coffee? HOLY CRAP, IT'S A SHARK! Yep, the bottom of this 3-1/4" tall, porcelain mug features the imposing head of a great white shark lunging up at you. A classic gag that's both funny and disconcerting. Dishwasher and microwave safe.
