Aaron Judge, excerpt from “The Tonight Show” by Jimmy Fallon

Aaron Judge went from dominating The Show to heist on “The Tonight Show”.

After the Yankees slugger American League MVP this week he was up for some fun with NBC host Jimmy Fallon.

Spies tell us only that Judge snuck into MLB NYC’s Midtown flagship store to join the former Saturday Night Live comic for a pre-recorded episode that will air on “The Tonight Show” later Friday night.

We hear that Judge was disguised as a referee while Fallon disguised as a catcher, with the pair pranking shoppers on the spot by revealing their true identities.

We heard they also posed in front of Yankees Stadium.

“It was so much fun,” said the insider of Friday’s stunt across the street from Fallon’s 30 Rock studios and Radio City Music Hall.

Some fans were apparently privy to the appearance as they lined up at the store waiting for Judge to appear.

This is not the first time the referee has acted this way went in disguise to a piece of Fallon comedy. In 2017, as a rookie, he went incognito as a man on the street to ask unsuspecting New Yorkers what they thought of him.

“I’m here at Bryant Park to see what Yankees fans think about Aaron Judge,” he said in the segment at the time. Although he was less known at the time, the typical response was, “I think Judge will be a star.”

He just had a historic break year AL’s Roger Maris’ 61-year home run record with 62 homers.
