Despite Ben Affleck’s most valiant efforts, his son has not adopted his rabid Boston sports fandom.

During an appearance on “Jimmy Kimmel Live!” Thursday to chat about his upcoming Netflix movie “Triple Frontier,” Affleck said that, prior to attending a World Series game with Kimmel and Matt Damon , he took his three children to see some baseball.

“On the way to the game, I was kind of giving my kids a pep talk,” Affleck said. “My kids, they’re 13, 10, and 6, about to be 7. And I was telling my 6-year-old, my son, particularly, ‘We’re really excited because we’re from Boston, and this is a big deal, and the Red Sox’ — and I’m giving him the whole history.

“He listens to me, and then he stops and goes, ‘Dad, you’re from Boston. I’m from LA,’ ” Affleck continued. “I had a full existential crisis. I failed. I’m a bad father. This is a disaster.”

Later in the segment, Affleck proved how hard he has tried to push his Boston fandom onto his son, showing photos of his son’s room decked out with a Patriots slide, a wall covered in Lombardi trophy decals, and a chair that looks like a giant, helmeted Tom Brady that Affleck said his ex-wife, Jennifer Garner, thinks is “creepy.”

“I think it’s totally appropriate for grown men to make totems and idols of other grown men and worship them,” Affleck joked.

Affleck and Kimmel also held a “retirement ceremony” for the end of Affleck’s run as Batman, hoisting a Batsuit with “Batfleck” and the No. 12 on the back to the studio rafters.

“That’s Brady’s number,” Affleck said when Kimmel asked why there was a No. 12 on his outfit. “You can’t be a hero without wearing number 12.”
