Car Accident Joke

A husband gets a phone call from the hospital saying that his wife has been involved in a car accident and she's in a coma.
He rushes to the hospital to be by her bedside and there he remains for over a week while the doctors are giving up hope but after being there for so long he was getting rather frisky so waits for the doctor to finish his checks and leave the room and his slips his hand under the covers and strokes his wife's leg when he thinks he sees her finger twitch. So he strokes her inner thigh moving upwards and he hears his wife moan. He rushes out of the room yelling for the doctor and tells him that what happened. The doctor takes him aside and suggests that if he tries oral sex, it may be bring his wife round and that he'll keep everyone out of the room so they can have some privacy. The husband excitedly goes into his wife's room and the doctors and nurses wait patiently outside in the corridor.
A few minutes later the guy comes out looking pale, the doctor says
"What's the matter?"
"She's dead"
"Well didn't you do as I suggested?"
"Yes Doctor but she choked!"
