A patient goes to the doctor's office where, much to his surprise the doctor asks him, "Would you please help me with a problem I'm having?"

Sure, doctor, what can I do for you, says the patient.

"Would you scream in the most earsplitting, piercing screams you can manage? Try to make it sound as if you're in terrible pain." The doctor says.

"But why, doctor, you've always been gentle with me and your treatments have never caused me any pain?" Asks the patient.

"Yes," Says the doctor in a matter-of-fact tone, "but I have a 4 o'clock tee time at the golf course I don't want to miss, and my waiting room is still full of patients."
