Parkour on a bike, with Band of Horses
I totally sound like an old fogey saying this, but KIDS THESE DAYS ARE CRAZY. Check out this amazing video of Scottish biker Danny MacAskill, essentially doing parkour on a bicycle. Stay for the whole thing - around 3 minutes in, he starts doing stuff that literally made me gasp. Soundtrack is the excellent song "A Funeral" by WFPK favorite Band of Horses.
By contrast, here's how they did the bicycle crazyness back in Thomas Edison's day - he's the cameraman on this one, from 1899. Still way more impressive than anything I can do, by a mile.
