Why can't the Cubs win?
How did Paris Hilton and Snooki ever get famous?
Some things are just inexplicable. You want to know the answers but you may be afraid to ask the question. An important thing to remember is never ask a question that you don't want to know the answer to.
For example, when I was in medical school I was doing a history and physical examination on a prison inmate who was admitted to the prison ward at the hospital. After I was done, my curiosity got the better of me and I asked him why he had been incarcerated. He looked around, leaned in close to me, and whispered,
"It was for sexual crimes, but please don't tell the nurses."
That's the last time I asked that question.
Other times, it's clear the question just shouldn't be asked. I had a car accident victim come into my trauma bay recently, and we are supposed to disrobe everyone completely to do a full exam. Sometimes things get skipped, and this guy's underwear stayed on while his pelvis Xray was shot. Here it is:
That ring on the bottom of the picture is outside his pelvis. Outside his body. But it's right at the base of the penis. Have you guessed yet what it is?
It's a cock ring. He was driving alone...wearing a cock ring. Why, you may ask? I didn't ask the question.
