Stephen Colbert delivered a surprise monologue from his bathtub before Monday's Late Show rerun

The Daily Beast

"Last week, after taping one final audience-free episode with Dr. Sanjay Gupta as his one and only guest, Stephen Colbert announced that production on The Late Show would be shutting down until further notice," says Matt Wilstein of Colbert's monologue, which The Late Show host teased on Twitter shortly before airtime. "But if you tuned into CBS at his regular 11:35 p.m. time slot Monday night, there he was. After humming his own theme song, Colbert emerged from inside his own bathtub to deliver one of the strangest late-night monologues in recent memory."
