So a woman had been in a coma for a few years. . .

And everyday, when the nurse comes in to bathe her, she notices slight changes in her vital stats whenever she washes near her crotch. So the nurse fetches the woman's husband and says,
"I think a little oral sex is all your wife needs to come out of this coma."
The husband nods and asks for a little privacy. The nurse leaves, but after a few minutes she hears a horrible clatter followed by the woman flat-lining. The nurse runs in and yells,
"What the hell happened?"
The husband replied, "I don't know! I think she choked!"
