A sushi plate simply doesn't come any more terrifyingly awesome than this.
This great white sushi plate, created by deviantART user Aviceramics, has you dipping your delicious sushi right into the mouth of the beast. In this case, diners will fill the shark's mouth with soy sauce or other sushi-appropriate condiments. It's a good thing that sushi is eaten with chopsticks, because I sure wouldn't want to stick my fingers in there. I don't care that it's made out of motionless ceramics, those jaws of death look like they'd snap shut at any moment, especially since you're dipping fish food into it as you eat.
If you want a sushi plate that will make you afraid to go into the water afterwards, this is the product for you. You shouldn't go swimming after a big meal anyway, so why not enforce that rule with a little shark fin fear?
