Which reminds me of the one about the bloke who goes to see his doctor.
"Doc, I want to be castrated."
"What ?", says the doc, "are you absolutely sure ?"
"Oh yes", say the man, "I've talked it over with the wife, and even she agrees that it would be for the best."
"Ok", says the doc, "I guess you know your own mind - I'll refer you to the hospital, then."
At the hospital, exactly the same conversation takes place with the nurse/ receptionist, and again with the consultant physician.
The day of the operation arrives, and as he's wheeled into the operating theatre, the surgeon warns him that castration is an irreversible operation.
"No worries", says the man, "I've been asked about this time and time again - my mind's quite made up." And so saying, the anaesthetic begins to work, and the man passes out.
Some time later, he 'comes to' whilst being wheeled back to the ward from theatre, and looks down to see quite a large dressing is in place.
He comments on this to the theatre porter, who replies that this was a very unusual operation.
"Indeed, I've never seen anyone have a castration here before", he says, "most people come in here for a circumcision."
"THAT'S IT !", cries the bloke on the trolley, "that's it - THAT'S THE WORD - 'CIRCUMCISION'."
