"Doc, I think my son has VD," a patient tells his urologist on the phone. "The only woman he's screwed is our maid."
"Okay, don't be hard on him. He's just a kid," the medic soothed. "Get him in here right away and I will take care of him."
"But I've been screwing the maid too, and I've got the same symptoms that 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 has it too."
"Oh crap!" the physician roared, "That means we've all got it!"
