A fisherman was selling live crabs in the market. An old woman went up to him and looked at one bucket of crabs while he removed the cover to show her the other bucket of crabs. She asked, "Why do you have that bucket of crabs covered but not this one?" He replied, "Bueno, the bucket with the cover has North American crabs. If I don't keep it covered, they work together to build a chain to the top of the bucket and help all the others climb out to freedom. I've lost so many gringo crabs that way." The woman asked, "But what about the other kind? Don't they climb out, too?" He sighed and smiled, "No, these are Honduran crabs. Whenever one tries to climb to the top, the others just pull him back into the bucket."
