Conan

The cast of 'Orange Is the New Black' -- including Taylor Schilling, Jason Biggs, Kate Mulgrew, Natasha Lyonne, Laverne Cox and Uzo Aduba -- took over 'Conan' last night, and when they weren't busy making everyone laugh, they were caught up in terrifying Conan O'Brien and sort of beating him into submission.

If you've never seen the movie 'This Is Spinal Tap,' then Fall Out Boy's performance of 'My Songs Know What You Did on 'Conan' last night probably made little-to-no-sense to you. The Chicago band recreated a scene from the 1984 mockumentary when the Spinal Tap bassist, played by Harry Shearer, got trapped in a theatrical pod that the band was using on stage.
