Any Physicians Out There?

I have a question for any physicians in the crowd.

Last week, I went to a new doctor for a physical. It had been a long time since I had one so I didn?t quite know what to expect.

The nurse did all the blood work and other stuff and then told me to strip down and wait on the doc. So, I?m sitting there in this tiny, COLD room, stark naked, only covered by a stupid little crotch-sized blue blanket thing.

After about twenty minutes of this, the doctor comes in and I can?t help but notice that he has a confused look on his face. He reaches out and shakes my hand and introduces himself. (I usually don?t like to be naked the first time I meet someone.)

He then starts his normal checkup, checking lungs, throat, ears, etc. Thankfully, no poking or prodding involved. He then shakes my hand again, and walks out the door.
I think I even saw a smirk on his face as he walked out the door.

My question to you is, Why the hell do I have to be butt naked for this procedure?
