Jerry O’Connell Documents 18-Inning World Series Game Experience, ‘I Have To S***’

Folks got two World Series games in one as the Dodgers needed 18 innings to beat the Blue Jays … but Jerry O’Connell wasn’t gonna miss a single moment of action — even though he REALLY had to take a dump.

The actor documented his entire Monday night at the ballpark on his social media page … initially smiling from ear-to-ear as he made his way to Game 3 of the Fall Classic.

JOC was all-in on the experience … even playfully jawing at visiting Jays fans in the crowd early in the contest.

Little did he know, the “Kangaroo Jack” star — who is married to supermodel and actress Rebecca Romijn — was in for a LONG night … and his pep started to sputter as the game went into extras.

O’Connell made it clear he was going to remain seated, though … doing his best ‘Wolf of Wall Street’ impression and proclaiming he wasn’t “f***ing leaving.”

When one follower tried to downplay his loyalty, JOC explained he was sacrificing a lot more than sleep.

“Bro. I’ve been here since 4 and I have to s***,” he said.

In the 17th(!!!) inning, JOC took a selfie video to make it clear he was going to “outlast [Jason] Bateman” … who toughed it out, but certainly looked worse for wear in his seats closer to the field.

It was such a daunting night, O’Connell even showed how one fan opted to tune in to a police chase on his phone to get through it.

Thankfully for Jerry’s sanity, it was all worth it … as Freddie Freeman put an end to the madness with a walk-off homer to centerfield in the bottom of the 18th to give L.A. a 2-1 lead in the series.

O’Connell got footage of the highlight and his reaction … celebrating both the dinger and the fact he could finally go home and, we’re assuming, handle his business.
