Matt Damon, Ben Affleck, John Krasinski and others turned on their best Boston accents on Jimmy Kimmel Live to throw support behind Tom Brady and the New England Patriots on Thursday in a new Super Bowl sketch, “I Am the Locker Room Guy.”

Technically, however, it was “Donald O’Donnell McDonald,” “Ryan Salty Flannigan” and others who took turns confessing to deflating the footballs during the AFC Championship Game on Jan. 18.

“I deflated those balls myself, all right? I did it. I’m the perpetrator. If you don’t believe me, there’s nothing I can say to change your mind. I’m turning myself in!” Affleck, a.k.a. Ryan Salty Flannigan, said in his on-camera testimony.

Steven Tyler, Eli Roth, Dicky Barrett and Bill Simmons also appeared in the sketch.

And Kimmel made sure to chime in at the end with a playful jab at Damon when he admitted to “acting alone.”

“Do you know why you acted alone? Because nobody wants to act with you!” Kimmel joked.
