Do you like improvisational theater? How about professional comedians? Free stuff? Umm, yes, of course and duh. Which is great because K.A.R.L. Improv is bringing the Upright Citizen’s Brigade (UCB) Touring Company to Brown Hall 100 tonight. UCB has spawned the likes of “SNL” alumn and “Parks and Recreation” star Amy Poehler; “Scrubs” janitor Neil Flynn; Jack McBryer; the submissive, naïve Kenneth Parcells on “30 Rock”; and many “Daily Show” alums, including Ed Helms, Rob Corddry and Rob Riggle.

The Upright Citizen’s Brigade is based in both New York City and Los Angeles and is one of the top improv theaters in the country—on par with The Second City and the Groundlings.

Unlike the short-form improv (think “Whose Line Is It Anyway?”) that K.A.R.L. will perform for 15 minutes to open the show, UCB’s style is long-form. Their process is more similar to a play in which the characters, settings and themes remain consistent throughout the entire show. Despite their differences in style, “[UBC’s] sense of humor is K.A.R.L.-esque: a little more offbeat,” said senior Michael Greenwald, K.A.R.L. treasurer.

And given UCB’s track record, there’s a good chance a performer you see on Friday night will be famous sometime soon.

K.A.R.L. is also having its annual Dance Marathon fundraising show next Friday—same time, same place. “We make it so easy for people,” Greenwald said.

If you want a sense of K.A.R.L.’s humor, their show, which is raising money for chronically ill children, is called “A Dance Panda-emic: THE FEVER IS SPREADING.”

K.A.R.L. and the UCB Touring Co. will perform Friday for free at 8 p.m. in Brown Hall 100. On Oct. 8, also at 8 p.m., K.A.R.L. will be putting on “A Dance Panda-emic” to raise money for Dance Marathon in Brown 100. Tickets for that show will be $5.
