I've done that once.
Back in High School, I was in marching band. You don't turn, you "pivot", while at the same time kicking out a foot for the next beat/step. Well, I was in my living room, and pivoted to go back to my bedroom. I thought I just in front of the hallway. WRONG! I was, in fact, next to the wall, which I promptly kicked with my foot. I managed to break a toe. What's worse, I had to march on a broken toe until it healed.
