The war of words was so incredible, it might even be the best "Drop The Mic" duel to date -- and it wasn't even on TBS, but on "The Late Late Show." (If you didn't know "Drop the Mic" was created by Corden, as it's based on the popular segment on his show.)
"People came to see Peter Rabbit battle me, but your battle's with your lady -- her Rabbit's out of batteries," Kutcher quipped back. "My career's been doing fine ever since the 70s, your job's an Uber driver for real celebrities."
"People see me at valet. They say, 'Look, it's a star.' They see you at valet -- they say, 'Dude, where's my car?'"
Corden was calm, cool, and collected, but was ready jab back.
"You made fun of Peter Rabbit and my work on Carpool. I'm not taking that from the tool that made trucker hats cool," he said. "You joined Two and a Half Men when producers had a beef, it's the only time people thought, man I miss Charlie Sheen. You invested all your money in technology and apps. Hell I'd do the same if I knew I couldn't act."
Kutcher came back with jabs about "Ocean's 8" and Corden's weight.
"You did Ocean's 8 that's worth mentioning, probably should have called it Ocean's ate everything...and before that you did so many animated flicks, that we haven't seen this face in a movie since we last saw your d--k."
Since this was, like we said, one of the most heated "Drop the Mic" battles in history, they needed a proper judge to choose the winner. Who would be better than Diddy?
