A lady goes to the doctor and complains her husband is losing interest in sex. He gives her a pill but warns her that it's still experimental. He tells her to slip it in his mashed potatoes at dinner. At dinner that night, she does just that.

About a week later she's back at the doctor and tells him, "The pill worked great! I put it in his mashed potatoes like you said. It wasn't five minutes later that he jumped up, pushed all the food and dishes to the floor, grabbed me, ripped off all my clothes and ravaged me right there on the table."

The doctor says, "Oh dear -- I'm sorry, we didn't realize the pill was that strong. The foundation will be glad to pay for any damages."

The lady replied, "Nah, that's okay. We're not welcome back at Denny's anyway."
