A man enters the hospital for a circumcision. When he comes to after the procedure, he�s perturbed to see several doctors standing around his bed. 'Son, there�s been a bit of a mix-up,' admits the surgeon. 'I�m afraid there was an accident, and we were forced to perform a sex-change operation. You now have a vagina instead of a penis.' 'What!' gasps the patient. 'You mean I�ll never experience another erection?' 'Oh, you might,' the surgeon reassures him. 'Just not yours.'
