Beverly Hills, 90210 - Season 1 Episode 16 Fame Is Where You Find It

Brandon is rollerblading in the park while the television show Keep It Together is filming an episode. The producers seek him out as an emergency replacement for one of the extras. He hits it off with the star, Lydia Leeds, and is considered for a recurring role. However, Lydia is only using him to make her leading man/boyfriend jealous so that he will end his holdout. Brenda fills in for Brandon at the Peach Pit. She is in over her head until she adopts the persona of Laverne, a sassy, gum-chomping waitress. She quickly charms all of the customers with her wisecracks and lip-synch routines.
