Rock has underbid outside companies to take over production of Milton's pet food commercials. He wants to expand his creativity as a director, and he figures being involved in "the real deal" is the best way to do it. He then proceeds to pull Sasha literally off the street to star in his first Canine Cibble commercial.
The problems start immediately when it's discovered Sasha is allergic to Canine Cibble. Rock then gets a bad replacement script, leading to him firing his writer. This creates stress to complete the commercial for the Macy's Thanksgiving Day Parade. As it turns out, Sasha has a stash of spec scripts written for dog food commercials. When it comes time to shoot, Sasha gets stuck in a body stocking.
The final commercial shows a forlorn Sasha getting cut out of the body stocking, then seeing the Canine Cibble and getting excited. The tagline is "Escape - Canine Cibble". Rock's debriefing with the executive suggests the actual commercial was accidentally lost.
The ultimate commercial was popular, however. Rock takes a positive spin on the end result, but tosses the idea to parlay the commercial into a feature film.
