Sex Joke - Wife In Comma

A man was visiting his wife in hospital where she has been in a coma for several years. 

On this visit he decides to rub her left breast instead of just talking to her. On doing this she lets out a sigh. 

The man runs out and tells the doctor who says this is a good sign and suggests he should try rubbing her right breast to see if there is any reaction. The man goes in and rubs her right breast and this brings a moan.

From this, the doctor suggests that the man should go in and try oral sex, saying he will wait outside as it is a personal act and he doesn't want the man to be embarrassed. 

The man goes in then comes out about five minutes later, white as a sheet and tells the doctor his wife is dead. 

The doctor asks what happened to which the man replies: "She choked."
