We love us some Mary Lynn Rajskub. To the point of rushed-to-the-hospital exhaustion, really. If you know her work, you see that it's hard not to. Popular from her role as CTU techie geek Chloe O'Brien on 24, Rajskub is also known for playing one of Adam Sandler's sisters in Punch Drunk Love and part of the indie elite ensemble in . But we love her best from our initial introduction to her from Gilmore Girls as both a troubadour and Kirk's girlfriend. (The movie they made together was goddamn hysterical. Also: shut up.

SF Sketchfest presented two sold-out nights of "An Evening of Dr. Jonathan Katz Professional Therapist and Patients" this weekend at Eureka Theatre. We went on Friday night, when the “patients” were Maria Bamford, Brian Posehn, Bob Odenkirk, and “more,” which ended up being surprise guest, Robin Williams. The patients were delightfully quirky, and, as usual, Dr. Katz was the perfect springboard for their jokes. Those of you who went to Saturday night's show, let us know how it was and who the surprise guest was for the night! more ›
