Food
A woman asks her husband if he'd like some breakfast. "Would you like bacon and eggs, perhaps? A slice of toast and maybe some grapefruit and coffee?" she asks.
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 lunch time, she asks if he would like something. "A bowl of soup, homemade muffins, or a cheese sandwich?" she inquires. He declines. "The Viagra," he says, "really trashes my desire for food."
Come dinnertime, she asks if he wants anything to eat. "Would you like a juicy porterhouse steak and scrumptious apple pie? Or maybe a rotisserie chicken, or tasty stir fry?" He declines again. "Nah, still not hungry."
"Well," she said, "would you mind letting me up? I'm starving."
