This is a short video of an angry crab waving a knife at a guy. I don't care how delicious he might be, I would not mess with that crab. I like my fingers just the way they are: full length. "What about your pinky?" I've had to learn to love him the way he is.
Hit the jump for the video, then wish you had a pet knife-wielding crab.
Thanks to everyone who sent this, the majority of whom expressed an interest in starting an international knife-fighting crab league.
