A really bad, terrible mistake

Fred goes to a doctor and says, "Doc, I want to be castrated." Doc says, "Look, I don't know what kind of cult you're into or what your motives are, but I'm not going to do that sort of operation." Fred: "Doc, I just want to be castrated, and I'm a little embarrassed about talking about it, but I have $5,000 cash right here. Will you do it?" Doc says, "Well, OK, I guess I could make this one exception. I don't understand it, but OK." He puts Fred to sleep, does the trick, and is waiting at the bedside when Fred wakes up. "Well, Doc, how'd it go?" Fred asks. "It went fine, just fine. It's really not too difficult of an operation. As a matter of fact, $5,000 is a lot to pay for such a simple task, and I felt a little guilty about taking that much. So, while I was operating, I also noticed that you had never been circumcised, so I went ahead and did that, too. I think, it's really better for a man to be circumcised, and I hope you don't mind my..." "CIRCUMCISED!" yells Fred. "THAT'S the word!!!"
