Fish on Crab Violence

So, no idea why this was funny to me, but, this container had a BUNCH of live crabs in it, but all i could think was "Why the hell is there a fish on the crab case?" and then one of the guys who works there in the eatery by the tank comes out with HUGE/LONG tongs and grabs a few of them, and I've never seen legs work so fast in my life, which I thought was REALLY funny, for some reason, and then he plunked them in the bucket to bring them in, and there was a little boy looking down at the crabs to one side of the picture I took and was all like "BY CRABBIES!" it was so cute, cause he was like 3 years old
