Coma

A man is 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 his wife. He rushes out and tells the doctor. The doctor
says this is amazing and is a real breakthrough. Obviously the
sexual stimulation is getting through to the woman's brain. The
doctor then suggests 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 is shocked and asks what happened.

"She choked."
