“Doc, I think my son has gonorrhea,” a patient told his urologist on the phone. “The only woman he’s screwed is our maid.”

“OK, don’t be hard on him. He’s just a kid,” the doc soothed. “Get him in here right away and I’ll take care of him.”

“But, Doc, I’ve been screwing the maid, too, and I’ve got the same symptoms he has.”

“Then you come in with him and I’ll fix you both up,” replied the doctor.

“Well,” the man admitted, “I think my wife now has it, too.”

“Son of a bitch!” the physician roared. “That means we’ve all got it!”
