According to Hollywood.com Jack McBrayer, born on May 27, 1973 in Macon (Ga) "nurtured an interest in theater and performing since childhood. He attended the University of Evansville in Indiana, studying theater management, with an eye on honing business and management as well as dramatic skills, smartly, as a back-up plan." McBrayer later took classes at Second City and Improv Olympic in Chicago and eventually caught the attention of Tina Fey.
The plot of 30 Rock revolves around the cast and crew of the fictional sketch comedy series TGS with Tracy Jordan, that airs live from Rockefeller Center (30 "Rock" - get it?). McBrayer. is hilarious as an NBC page who acts as a go-fer for the various actors, writers and executives. He is absolutely thrilled to be working in TELEVISION and does it all, no matter how demeaning, with a big smile.
