One day, a forgetful professor was in the middle of a lecture when he noticed his students were staring at him, giggling. He paused, puzzled, then looked down and realized why: he was wearing mismatched shoes—one brown, one black. Embarrassed, he laughed it off and said, "Well, at least I'm prepared for any occasion!" The next day, he confidently walked into class with two identical shoes. Just as he was about to begin, a student raised her hand and asked, "Professor, is it your wife’s shoe this time?" He looked down and saw a tiny heel peeking out from under his pant leg. The professor sighed, "I guess I'll never walk a mile in my own shoes again!"
