Sitting Guy

A guy is sitting beside a lake, with a bucket of worms and a hammer. Another guy comes by and asks what he's doing. "I'm fishing," says the man. "How do you do that with just some worms and a hammer?" asks the second guy. The first guy replies, "Give me twenty dollars, and I will tell you." The passerby is most curious and hands over twenty dollars. "Well," says the first guy, "I throw a worm into the water, and as soon as a fish bites at it, I hit it on the head with my hammer." "Do you catch anything that way?" asks the other guy in amazement. "Oh yes," says the first man, "I've already made two hundred dollars this morning."
