The two were spotted at Dodger Stadium sporting t-shirts that read “I’m with stupid,” above an arrow pointing to the other, USA Today reported. Damon, the Boston native, wore a Red Sox hat, while Kimmel donned a blue Dodger hat. Actor Ben Affleck was with them but did not participate in the gag.
Damon and Kimmel have been engaged in a tongue-in-cheek feud for more than a decade.
The late night host earlier this month jokingly referred to Damon as “the most repugnant actor in the world” while recapping a Saturday Night Live skit in which Damon portrayed Supreme Court nominee Brett Kavanaugh.
The Red Sox defeated the Dodgers 5-1 to win the world series.
