Reminds me of two stories:-
Bloke talking to his mate says," I went to the surgery yesterday for a check up. He did quite a thorough examination including stucking his finger up me @rse. I think I'm going to change my dentist."
Young lady enters the dentist's surgery and says, "Do you know, sometimes I think I'd rather have a baby than have a tooth out."
Dentist replies, "Can you make your mind up fairly soon 'cos the chair has to go in a different position."
