The thinking man often rebuked his girlfriend because of her extravagance. Once he discovered four pairs of shoes in her room. “I also have four different kinds of feet,” she excused herself.

The thinking man laughed and asked: “So what do you do, when one pair is worn out?” At that, she realized he was not yet quite in the picture and said, “I made a mistake, I have five different kinds of feet.” With that the thinking man was finally in the picture.
