Last night on Late Night, Stephen Colbert and Jimmy Fallon took their rollercoaster love-hate frenemy-BFF relationship to a nice, happy place — in front of a piano for an “Ivory and Ivory” duet. And the conversation that led to the song went something like this: “So we’re not best friends?” asked Fallon. “No.” “And we’re not eternal enemies?” “No.” “So what are we?” Pause … “We’re friendly.” But, man, once they harmonized, you could really see the bromance sparkle, especially over the lovely hook: “If Rihanna and Chris Brown can be friendly, why can’t we?” Amen. Plus: Johnny Depp recounted the time he fell off of a speeding, uncontrollable horse while filming for The Lone Ranger. Instead of light at the end of the tunnel, he only saw “hooves.” Also: Mila Kunis tried, in as many synonyms and gestures she could muster, to one-up Conan’s assertion of harness-induced pain for men, while on the Late, Late Show with Craig Ferguson, Kunal Nayyar got very excited over the term, “clitoral stimulation.” Watch our compilation to see what you missed.
