A story about a pill

Doctor! Doctor!
A lady goes to the doctor and complains that her husband is losing interest in sex.
The doctor gives her a pill,
but warns her it is still experimental and tells her to slip it into his mashed potatoes at dinner.
So, that night at dinner, she does.
About a week later she's back at the doctor. She says, "Doc, the pill worked great!
I put it in the potatoes like you said!
It wasn't five minutes and he jumps up, rakes all the food and dishes on the floor,
grabs me, rips all my clothes off and ravages me right there on the table!"
The doctor says, "I'm sorry, we didn't realize the pill was that strong.
The foundation will be glad to pay for any damages."
"Naah... ", she says, "that's okay. We aren't going back to Sizzlers anyway."
