What will 10,000 downward-facing dogs look like? Find out at this megaclass on the Great Lawn, taught by Elena Brower, and hosted by Reggie Watts, the local stream-of-consciousness comedian who just opened for Conan O'Brien. Turn yourself into a human pretzel to the tunes of Buddy Wakefield, Wah!, O'Konsi Rhythms and other performers. (Mats will be provided by Jet Blue.)
