Consider the married couple who is out together on their luxury fishing boat. The husband usually takes the wheel, but he decides it's time for his wife to have a little practice in case there is ever an emergency.
"Please take the wheel, dear," he tells her. "Pretend I am having a heart attack and try to get the boat safely to shore."
So she drives the boat to shore.
Later that evening, when they're back home, the wife walks into the living room where her husband is watching television. She sits down next to him and switches the TV channel.
"What are you doing?" the husband asks.
"Please, dear, go into the kitchen," she says. "Pretend I'm having a heart attack. You must set the table, cook the dinner and wash the dishes."
