She was in the kitchen preparing to make soft-boiled eggs for breakfast. As he walked in she turned to him and said, "I want you to make love to me this very moment."
His eyes lit up and he thought: 'This is my lucky day.'
Not wanting to lose the opportunity, he embraced her and then gave it his all, right there on the kitchen table.
Afterwards she said, "Thank you darling" and returned to the cooker.
More than a little puzzled, he asked: "What was that all about?"
She replied: "The egg timer's broken."
