A man's wife had been in a coma in hospital for some time. As part of her continued care, her sheets were changed often and she was given sponge baths by a nurse.
During one of the sponge baths, the nurse noticed the wife reacted slightly when her private parts were washed.
The nurse spoke to the husband and explained that she had an unconventional idea that might bring his wife out of the coma. She explained the reaction and suggested that the husband should try oral sex with his wife.
He quickly decided to give it a try, and shut the door for some privacy. After a few minutes, the alarms on the life support equipment began to sound. The nurse rushed into the room and was shocked to find that wife was dead!
"What happened!" screamed the nurse.
"I don't know," said the husband. "She must have choked!"
