So the nurse calls the husband and says 'come down to the hospital, I think I know how to get your wife out of this coma.' so the husband hurries down, and asks the nurse what he can do.
The nurse says, 'I think that oral sex will bring her out of her coma, it will arouse her enough to bring her out of the coma.'
So the nurse closes the curtains, and leaves the husband with his wife in the room.
Moments later, the man comes running out of the room, flustered. The nurse, worried, asks him what happened.
The husband says, 'I don't know, I think that she started choking.'
