The scene: as I’m leaving my BFF’s apartment, I see a just-barely-toddler aged kid playing on the railing of the ramp next to the entrance stairs. Two 20-something dudes were exiting behind me. Dude #1: Whoa, bro. Look at that little guy. Dude #2: You go, baby. The whole world’s your junglegym. Dude #1: That kid’s like a baby parkour champion. Dude #2: Baby Parkour should be our new tumblr.
