This troper was once helping his wife with the chores. When she brought in the clean sheets from the laundry, I offered to help her make the bed. She quipped back, "And after you make your bed, you can lie in it." So, as soon as we were finished, I stretched across the bed, smiled up at her and said, "Gee, honey, you look like you've lost weight." (It took her a moment to figure it out ... and several hours to forgive me.)
