This week, Comedy Central and Outside Lands/Bonnaroo organizers Superfly announced Colossal Clusterfest, a three-day comedy festival in San Francisco that will feature a ton of famous comedians, musicians, and “iconic comedy attractions” based on South Park, It’s Always Sunny In Philadelphia, and Seinfeld—only one of which is actually a Comedy Central show. This news comes from a press release, which says the festival will be held at San Francisco’s Civic Center Plaza and Bill Graham Civic Auditorium from June 2 to June 4, ending with a “live on-air Comedy Central special.”
