Rednecks Go Fishing
Two rednecks go on a fishing trip. They rent all the equipment - the reels, the rods, the wading suits, the rowboat, the car, and even a cabin in the woods. I mean they spend a fortune!
The first day they go fishing, but they don't catch anything. The same thing happens on the second day, and on the third day. It goes on like this until finally, on the last day of their vacation, one of the men catches a fish.
As they're driving home they're really depressed. One guy turns to the other and says, "Do you realize that this one lousy fish we caught cost us fifteen hundred bucks?"
The other guy says, "Wow! Then it's a good thing we didn't catch any more!"

Joseph WolpeDied 4 Dec 1997 at age 82 (born 20 Apr 1915).South African-born American psychotherapist who helped usher in cognitive behavioral therapy during the 1960s; he devised a treatment to help desensitize patients with phobias by exposing them to their fears incrementally. He worked on systematic desensitization with a methodology designed to treat people with extreme anxiety about specific events, situations, things, or people. His approach involved developing a hierarchy of anxiety-provoking situations, learning relaxation techniques, then associating these situations with relaxation, beginning at the bottom, or least anxiety-provoking, part of the hierarchy. He founded the Association for Advancement of Behaviour Therapy and the Journal of Behavior Therapy. |
