"An Evening of a Thousand Scowls: 826 Valencia's Fourth Annual Comedy Night"

PREVIEW If laughs were a dime a dozen, then even the cheapest ticket to 826 Valencia's fourth annual comedy night would guarantee a busted gut. This year's "Evening of a Thousand Scowls" features some of today's brightest and most riotous funny people, including Sarah Silverman (writer and star of Sarah Silverman: Jesus Is Magic), Jimmy Kimmel (Jimmy Kimmel Live and The Man Show), Patton Oswalt (actor and stand-up comedian, as seen on HBO and Comedy Central, Seinfeld, and King of Queens), Zach Galifianakis (stand-up comedian, Boston Common, and Tru Calling), and Al Madrigal, an award-winning Bay Area comedian and founder of 826 Valencia's Comedy Night. All proceeds benefit 826 Valencia's free student programming and the 826 Writers' Room at Everett Middle School. (Jenny Miyasaki)
