A male doctor and a female doctor meet at a medical convention. One thing leads to another and they end up in bed. The male doctor is a somewhat snotty type and says to the female doctor:" You wash your hands all the time. I bet you're a surgeon". The female doctor agrees that she is, indeed, a surgeon. Because she is a little ticked off by this guy's manner after lovemaking, she says: " I bet I can guess what your specialty is - you're an anesthesioligist". The male doctor is astounded. He says:" You're right! How did you know that?'

The lady says: " I didn't feel a thing"
