A bloke goes to the doctor's and asks to see someone about a problem with his manhood. The doctor is busy so he is ushered in to the practice nurse.
He's reluctant to strip down in font of her as he says he thinks she will laugh, but she assures him that she has been a nurse for more than 20 years and will view his problem dispassionately.
So the bloke drops his gear revealing something the size of a AA battery and the nurse falls about in hysterics. The chap's very angry but the nurse pulls herself together, wipes her eyes apologizing profusely and asks what the problem is.
"Problem!?" the bloke explodes. "Call yourself a health professional? Can't you see how swollen it is!?"
