I've seen a YouTube video where a set of male equipment gets turned outside-in to form lady parts. It was only a computer graphic, not a live surgery, fortunately. I don't think my gag reflex could have handled it, otherwise.
The turn-of-the-millennium wasn't much better. I had to sit through a 15-minute video with 20 other boys (Fourth and Fifth grades merged). Instead of providing answers, it just created more questions in my head. Private elementary schools suck. Thank God I managed to convince my parents to let me take Grades 7 - 12 at a public school.
