A woman asks her husband at breakfast time, "Would you like some bacon and eggs, a slice of toast, and maybe some grapefruit juice and coffee?"
He declines. "Thanks for asking, but I'm not hungry right now. It's this Viagra," he says. "It's really taken the edge off my appetite.
At lunchtime, she asks him if he'd like something.
"How about a bowl of soup, homemade muffins, or a cheese sandwich?"
He declines. "The Viagra," he says, "really trashes my desire for food.
Come dinner time, she asks if he wants anything to eat. "Would you like a juicy rib eye steak and some scrumptious apple pie? Or maybe a rotisserie chicken or tasty stir fry?"
He declines again. "No," he says, "it's got to be the Viagra. I'm still not hungry."
"Well," she says, "Would you mind letting me up? I'm starving."
