A young new doctor was doing his residency in OB, but he was quite embarrassed about performing female pelvic exams. To hide his embarrassment, he had unconsciously formed a habit of whistling. One day, while performing this exam on a middle-aged lady, his patient suddenly burst out laughing and further embarrassed 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.'"
