With only 10 episodes of “The Colbert Report” left, it makes sense that one of Stephen’s oldest friends would pop by for a visit.

Colbert’s old Second City and “Strangers with Candy” buddy, Amy Sedaris, “surprised” him on Wednesday night with a chip on her shoulder about being bumped for Christopher Nolan. After ribbing Colbert and plugging the new season of her Adult Swim show, “The Heart, She Holler,” Sedaris treated the audience to a clip from “Interstellar” that literally no one had seen before (because it’s definitely not from “Interstellar”).

Watch the clip to see the adorable friendship between Colbert and Sedaris in action, plus a whole lot of tap dancing in space.
