A man goes to the doctor and says “Doc, I want to be castrated!”
The doctor says “Why? You should know that this operation is painful and irreversible.”
So the man replies “Doc, this is my business – I’ll pay what you will charge me – please go ahead.”
After the doctor has finished the operation he asks the man:
“Now that you got what you wanted, will you tell me why you asked for it?”
“Very simple”, says the man, “I’m going to marry a Jewish girl.”
Doctor said “So perhaps you wanted to be circumcised?”
“Ah”, says the man, “that’s the bloody word!”
