BBC Two is showing a documentary called “South Pacific” that has nothing to do with World War II or washing a man right out of someone’s hair. What it is about, at least partially: surfing. And this slo-mo HD clip of surfer Dylan Longbottom (hee!) going through a barrel wave is too awesome for words. This is a great time to be unemployed, because if you are: click on the HD button, go to full-screen, and smoke all the pot in your apartment. So much better than a paycheck.
