Chuck Norris – Dodgeball: A True Underdog Story

This lovable sports comedy arguably has one of the most random cameos in this gallery. At the film's climax, Vince Vaughn's Average Joe's needs a forfeit decision overturned by the ruling committee in order to play against Ben Stiller's Globo Gym, with a two-thirds majority vote. That vote would come down to a tie-breaking vote by none other than action star Chuck Norris, ruling in Vince Vaughn's favor, leading to the climactic dodgeball match. Audiences would have already been shocked to have seen Lance Armstrong in the previous scene, but this random appearance by Chuck Norris easily tops that cameo.
