The Queen was visiting a hospital and stopped by one of the beds to speak to the man lying there.
"What is wrong with you, sir?" she asked the man.
"I got a wart on my balls," he replied, much to the consternation of the nurses. One of the nurses immediately rushed over to him.
"You can't say that to the Queen!" the nurse whispered.
"Well, what should I have said, then?" replied the patient.
"Something like you have a bruise on your back, or a cut on your arm, or a graze on your knee. Anything but 'I have a wart on my balls'!" answered the nurse.
Two months later, Princess Anne was visiting the same hospital and just happened to pass the same bed with the same man in it.
"What is wrong with you, sir?" asked the princess.
"Er... I have a bruise on my back," replied the man.
"Oh," the princess answered. "I'm so glad that your balls are better... I'll tell the Queen."
