the late Del Close in 'Ferris Bueller's Day Off'
Del Close

The Upright Citizens Brigade's annual Del Close Marathon will feature 575 improv shows from June 26-28, happening around-the-clock on nine stages across seven locations: UCB Chelsea, UCB East, Theater for the New City, 4th Street Theatre, Magnet Theater, SVA Theatre and FIT Haft Auditorium. You can buy a $35 wristband at UCB Chelsea starting June 26 at noon, and that gets you into every show (subject to capacity, of course). The only shows with advance tickets are the higher-profile, bigger shows at SVA and FIT, which include:

FRIDAY 6/26: Broad City Live (sold out), an improv session with Key & Peele writers, Horatio Sanz's "The Hooray Show"; and improv with the cast of Silicon Valley.

SATURDAY 6/27: Nick Kroll & Friends, an improv show with The Daily Show writers; Mad Men finale scene-stealer Brett Gelman's Gelmania! Live!, and an improvised show with Comedy Bang! Bang! writers.

SUNDAY 6/28: a special preview screening of Thank You Del Close documentary and two editions of ASSSSCAT 3000 (7:30 PM sold out; 10 PM you can get tickets)

Non-ticketed events, most of which are only 30 minutes (some even less), include Tami Sagher and Chris Gethard (6/27, 3 PM at UCB Chelsea), "Mike Birbiglia's Dream" (6/27, 6:30 PM at UCB Chelsea), the writers of Late Night with Seth Meyers doing a show (6/27, 9:30 PM at Magnet Theatre), 30 Rock's Scott Adsit (6/28, 3:30 PM at UCB Chelsea), and an entirely improvised episode of Seinfeld (6/28, 4:30 PM at UCB Chelsea).

As this goes for three days straight, needless to say there is a lot more, so pour over the whole 2015 Del Close Marathon schedule.
