Jimmy Kimmel Traumatized From Last Year's Best Picture Mix-Up in Oscars Promo

"You know I dream about it every night," the comedian says in the promo below. "I can't even open the mail because of all the envelopes -- it just piles up."

As Kimmel reclines further back into a therapist's chair, he gets flashbacks of mail piling on his floor and baristas calling out the wrong name on his coffee order.

"I tried to get it passed me, you know? Put it behind me, but it just catches up to me," he continues. "I feel like I'm losing my mind. And then the worst part is -- they want me to do it again! So what do I do?"

The camera then pans over to a very special guest.

The 2017 Oscars will go down in history as one of the most memorable after "La La Land" almost took home Best Picture -- until it didn't. Warren Beatty and Faye Dunaway presented the night's biggest prize to the front-runner musical. The movie's producer was almost done with his acceptance speech when a bombshell -- which he then relayed to the audience -- was whispered into his ear: The real winner was "Moonlight."

It was one of the most shocking moments in Oscars history, and the fact that the underdog movie won the top prize made it all the more incredible.
