There was an episode of Medium last sesaon that was in old-fashioned red-and-blue 3D. Married With Children (the ep Assault and Batteries ), Third Rock From The Sun ( Nightmare on Dick Street ), and Power Rangers ( Triple Force/Trakeena's Revenge, initially direct-to-video), have had 3D episodes as well, though they use a different type of 3-D spectacles (not red and blue but lenses of different shades, what they call Pulfrich glasses ).
