"Doc, I think my son has an STD,” a man tells his urologist on the phone. “Luckily, the only woman he’s screwed is our maid.”
“OK, don’t be hard on him. He’s just a kid,” the medic soothes. “Get him in here right away and I’ll take care of him.”
“But I’ve been screwing the maid too,” the man continues. “And I’ve got the same symptoms my son has.”
“Then come in with him and I’ll fix you both up,” replies the doctor.
“Well,” the man admits, “I think my wife has it too.”
“Oh, crap!” the physician roars. “That means we’ve all got it!”
