The man, exhausted, sleeps in the waiting room as the nurse gives his wife a towel bath. As the nurse does this, she notices a slight movement from the comatose woman as she runs the washcloth over the woman's private parts.
The nurse gently wakes the man up, and as he rubs sleep from his eyes, she tells him, "I noticed something when bathing your wife, and it makes me think she might respond to oral sex."
The man thinks a moment, then says, "OK, I'll give it a try." He goes into the room while the nurse watches the woman's vital signs from the monitor at the nurse's station.
Suddenly, the heart monitor goes flat with a loud "BEEEEP". The nurse charges off and almost crashes into the man as he exits the door of the woman's room. "What happened!?" she shouted.
"She choked."
