Walking and Stair climbing

Confession: If I were more tech-savvy, we would have more tape of Jack walking. Instead (because I started recording when I thought I had stopped recording), we have about 5 minutes of my foot with me, Jon and Jack all laughing in the background. And, while that, I'm sure is entertaining for some, it ended up on the cutting room floor.
Without further delay...here's Jack walking. No need to cover your eyes or gasp...he is unharmed in this clip.
