The 16th Annual Del Close Marathon

This annual celebration in honor of long-form improvisation's mad guru, Del Close, is many things: 56 continuous hours of staged silliness, a chance to spot visiting comedy names in signature shows or weird one-off happenings, a bacchanalian summer camp for performers and an endurance contest for stalwart audience members. A weekend pass gets you into anything on smaller stages, space pending; individual tickets for shows on bigger stages cost a bit more. As always, star-studded ASSSSCAT 3000 shows close out the weekend. More details will be revealed at ucbtheatre.com and, eventually, delclosemarathon.com.
