A woman asks her husband if he'd like some breakfast; bacon, eggs,
perhaps a slice of toast? Grapefruit with coffee to follow? 
He declines. "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 home made
soup, maybe, with a cheese sandwich? Perhaps a plate of snacks and a
glass of milk? 
He declines. "It's this Viagra," he says, "It's really taken the edge
off my appetite." 
Come tea time, she asks if he wants anything to eat. She'll go to the
cafe and buy him a burger. Maybe a steak and cheese pie? Pizza? 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 getting off me? I'm fucking starving!"
