Stephen Colbert's final weeks on The Late Show include a penultimate episode where he sat in the hot seat himself, answering the famous Colbert Questionnaire with help from an all-star lineup of his most celebrated guests.

Billy Crystal, Robert De Niro, Martha Stewart, Mark Hamill, Josh Brolin, Tiffany Haddish, Ben Stiller, Aubrey Plaza, James Taylor, Jeff Daniels, Jim Gaffigan, Amy Sedaris, "Weird Al" Yankovic, and Colbert's wife Evie took turns asking him the show's signature 15 questions. Former CBS Evening News anchor John Dickerson, a longtime friend, presided.

When asked about the best sandwich, Colbert chose Katz's Deli's hot pastrami. Josh Brolin's scariest animal? Trapdoor spiders. Mark Hamill asked if Colbert had ever sought an autograph himself.

Colbert revealed he owns a framed headshot signed by Steve Martin hanging in his office. It is positioned where a clock used to be, so he checks it to see the time. "It's always Steve Martin o'clock," he said.

Jeff Daniels learned Colbert is a Raiders of the Lost Ark purist. Tiffany Haddish discovered he has "the bladder of a baby chipmunk" and demands aisle seats on planes. When his wife Evie asked about his favorite smell, Colbert spoke about her rose lotion post-shower.

The episode brought together comedy and personal reflection for a farewell that mixed humor with genuine moments.
