[S4E10] Cowboy Aerobics And 473 Grease-Free Bolts !!LINK!!
Though we've all seen him achieve great success in movies, television, and music, there's one thing left for David Hasselhoff to conquer: exercise videos. The "Baywatch" and "Knight Rider" star made an unexpected cameo appearance in Season 4, Episode 10 ("Cowboy Aerobics and 473 Grease-Free Bolts") when Sheldon's acting teacher Gene Lundy (Jason Alexander) meets David Hasselhoff to pitch a workout tape starring Hasselhoff as the frontman in all his 90s-mullet-haired glory. The workout tape, titled "Cowboy Aerobics," shows The Hoff (a name he insists Lundy call him by) in a cowboy get-up doing aerobics alongside two young and attractive cowgirls in the backdrop of a western saloon bar.
