A new, young M.D. doing his residency in obstetrics was quite embarrassed to perform female pelvic exams. To cover his embarrassment, he had unconsciously formed a habit of whistling softly during the exam. One day, the middle-aged lady upon whom he was performing an exam suddenly burst out laughing, further embarrassing him. He looked up from his work and sheepishly said, "I'm sorry, was I tickling you?" She replied, "No, doctor, but the song you were whistling was 'I wish I was an Oscar Meyer Wiener'."
