Del Close Marathon 15th anniversary highlights (slide show)

The improvised Del Close Marathon's 15th anniversary began with a surprise announcement from the UCB Four (Matt Besser, Ian Roberts, Matt Walsh and Amy Poehler) that their long-awaited book, The Upright Citizens Brigade Comedy Improvisation Manual, was finally ready. The marathon ended some 56 hours later with a packed ASSSSCAT jam in the group's Chelsea space on 26th Street. Those that witnessed the funny and strange things that happened in between may have a hard time explaining everything to their friends, but these pictures from photographer Ari Scott should lend a hand.
