Turkey Day was an annual Thanksgiving Day marathon of MST3K episodes on Comedy Central, first held in 1991 to commemorate the show's third anniversary. Special bumper segments were shown between episodes, and each Turkey Day marathon from 1992 onwards featured the premiere showing of at least one new episode.
