A worried father calls the family doctor because he thinks his teen son has caught a venereal disease.
“I think he got it from the maid,”
says the concerned dad,
“and I’ve also been sleeping with the maid.”
“Okay,” the doctor replies calmly.
“Well, when you bring him into the office we’ll take a look at you as well.”
“And that’s not all,” the father continues.
“I think I might have given it to his mother.”
“Oh no!” cries the doctor. “Well, now we might all have it!”
