A woman asks her husband if he'd like some breakfast. "Would you like 
bacon and eggs, perhaps? A slice of toast? Grapefruit and coffee to 
follow?" she asks. He declines. "It's this Viagra," he says, "It's
really taken the edge off my appetite." 

At lunchtime, she asks if he would like something. "A bowl of home- 
made soup, home-made muffins or a cheese sandwich?" she inquires. 
He declines. "It's this Viagra," he says, "It's really taken the edge 
off my appetite." 

Come dinnertime, she asks if he wants anything to eat. She'll go to 
the store and buy him some food. "Would you like maybe a steak and 
apple pie? Maybe you'd like a pizza micro waved or a tasty stir-fry? 
That would only take a couple of minutes." He declines. "It's this 
Viagra," he says, "It's really taken the edge off my appetite." 

"Well," she says, "would you mind letting me up, then? I'm starving!"
