Mary Lynn Rajskub was a fan favorite as ever-scowling computer genius Chloe O’Brian on Fox’s smash hit 24. The versatile actress has also showcased her range on both small screen (2 Broke Girls, Californication) and big (Julie and Julia, Little Miss Sunshine). But comedy fanatics remember her best for her roles in cult hit Mr. Show with Bob and David, where she perfected her sulky “too cool for school” persona and proved she can deadpan with the best of them. Dry wit, an acid tongue and expert eye-rolling became her signatures. Rajskub dives back into the comedy world with her stand-up session at the Irvine Improv.
