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 that it's still experimental.  He tells her to slip it into his mashed potatoes at dinner, so that night, she does just that.  About a week later, she's back at the doctor, where she says, "Doc, the pill worked great!  I put it in the potatoes just like you said!  It wasn't five minutes later that he jumped up, raked all the food and dishes onto the floor, grabbed me, ripped all of my clothes off and ravaged me right there on the table!"  The doctor says, "I'm sorry, we didn't realize the pill was that strong!  The company will be glad to pay for any damage."  "Nah," she says, "that's okay.  We're never going back to that restaurant anyway."
