Erection

“Doctor”, the embarrassed man said, “I have a sexual problem. I cannot get it up for my wife anymore.” 

“Mr. Jones, bring her back with you tomorrow, and let me see what I can do.” 

The next day the worried fellow returned with his wife. 

“Take off your clothes, Mrs. Jones, The doctor said. 

“Now turn all the way around. Lie down please. Uh-huh, I see. Okay, you may put your clothes back on.” 

The doctor took the husband aside. 

“You are in perfect health,” he said, “Your wife did not give me an erection either.”
