An 80-year-old-couple watching TV, the old man gets up from his chair and walks out of the room.
"Where are you going?" asks his wife.
"To the kitchen," he replies.
"Will you get me a bowl of ice cream?" she asks.
"Sure," he says.
She says, "Maybe you should write it down so you'll remember. You always forget."
"I'll remember," he says.
"Well, I would also like some strawberries on top," she says. "You had better write that down cause I know you'll forget."
"I can remember that, I'm not stupid," he says, as he begins to loose his patience. "You want a bowl of ice cream with strawberries."
"I would also like some whipped cream on top," she adds, "Now I know you are going to forget so you better write that down."
He starts getting mad and says, "I can remember all of that, I don't need to write that down! Why do you always nag me?" and he walks to the kitchen in a bad mood.
After about 20 minutes he returns from the kitchen and hands her a plate of bacon and eggs. She stares at the plate for a moment and says, "You see what I was talking about you senile old fool! You forgot my toast!"
