You guys gotta let that one go. I had to use crutches and wasn't told that's how it should be done when you get down to a single crutch. I got told how to work them without destroying the nerves in my arm pits when I needed both of them and gradually through rehab got down to one but never thought to ask how it should be done. When that pic first got theories thrown around I was in that camp until I did that thing called research and realized we were wrong. Sometimes a cigar is just a cigar my friend.
