For Ross Tinsley's audition, in Episode 303 he walked out on stage, said "Let's go for a ride!" and started slapping his hands together. Piers Morgan, Sharon Osbourne, and David Hasselhoff all quickly buzzed the act. He walked off the stage before the judges could vote, but he was eliminated from the competition. Since Ross Tinsley's occupation was listed as "Ballroom Dance Teacher" and he has a video of himself dancing on YouTube, there's a chance that had he been given enough time by the judges, his act would have been a dance act.
