A woman asks her husband if he'd like some breakfast-bacon, eggs, perhaps a slice of toast? An Aitken's buttery? Grapefruit with ginger and coffee to follow?

He declines. "It's this Viagra", he says. "It has really taken the edge off my appetite."

At lunch time, she asks if he would like something-a bowl of homemade soup, maybe, with (mmmm) a cheese sandwich? Perhaps a plate of snacks and a glass of milk?

He declines. "It's this Viagra", he says. "It has really taken the edge off my appetite."

Come tea time, she asks if he wants anything to eat. She offers to go to the cafe and buy him a burger supper. Maybe a red pudding or a steak pie? Maybe he'd like a pizza microwaved? 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 starving!"
