Parkour at Cliff House in San Francisco, Or Why I Don't Exercise

I'm pretty sure I could do parkour if I weren't so busy working, surfing the net, reading bad novels (I'm looking at you, Mr. Penumbra's 24-hour Bookstore), and drinking my way through the vineyards of the world. In lieu of actually engaging in any beneficial physical activity, I give you this: a video I found on the internet.
