Carol and her friends trudged up the endless flights of stairs to their NYC walk-up after a night out. Exhausted and in stitches from their antics, Carol whipped out her phone to capture a funny moment with her friend. But as she attempted to resume the climb, her boot betrayed her, sending her tumbling off the railing in a whirlwind of unexpected acrobatics.

My friends and I were coming back from a night out and we live in a walk up in NYC. Those steps are killer and you can see why. We were on our 3 set of flights of stairs and all exhausted. I started recording my friends because she was being funny and needed a break. when she stood back up and went to take the next step, her boot slipped off the step and she lost her balance. after trying to catch herself, she cartwheels off the railing. It happened so fast but that's why it was even caught on video.
