Mary Lynn Rajskub

In many ways, it's odd that Mary Lynn Rajskub got the part of Jack Bauer's smartass tech guru on 24. For one thing, Rajskub started out as a painter-turned-performance artist; she got into comedy via performance art, a background that unsurprisingly helped land her a gig on the beloved sketch showMr. Show for its first two seasons. After that, Rajskub had a fairly typical career until 24, full of small parts on a variety of TV shows and films, including a recent guest spot on It’s Always Sunny In Philadelphia. Despite such scene-stealing roles on television, Rajskub excels most in comedy, performing regularly in L.A. and touring steadily.
