Viagra
 

A woman asks her husband, "Would you like some bacon and eggs? A slice
of toast and maybe Some grapefruit 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 asked if he would like something. "A bowl of soup,
homemade muffins, or a cheese sandwich?"
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. "Naw, still not hungry."

"Well," she says, "Would you mind letting me up? I'm starving."
