Pretty funny story I read on el inter web, enjoy:
I arrived at my doctor's office for a routine physical and everything was going fine. My previous conditions had all gone away and we were wrapping up when my doctor (female by the way, I am male) told me that she was "Going to need to check me for an enema." She turned away for a moment to put on some gloves as she did so I stood up, took off my pants, and bent over.
I misheard her. One does not "check" for an enema. One checks for a hernia.
The moment she turned around I heard "Oh sweet Jesus, what!" and I immediately realized my mistake. I quickly turned around to see my now bright-red doctor flushing over the completely unprecedented sight of my anus pointed in her direction. I began to apologize profusely and what followed can only be described as an extremely awkward check for testicular cancer and a hasty departure on her part. Needless to say I, too, got out of there as quickly as possible.
