 I had started selling shoes when I was about 14 years old in my father's store, and I began asking myself, what in the hell is a wall stretcher? What could a wall stretcher possibly do? I was pretty convinced by the time I reached the other store that it was a practical joke. When I got to the store, I found a young guy like me and asked him, and he confirmed my suspicion. Wall stretcher, though, it's actually pretty funny. Like, what would that do?
