Long before Paul Rudd was a Hollywood star, he was a diehard Kansas City Royals fan.
That's why after his team ended 30 years of frustration with its World Series win against the New York Mets Sunday, the actor partied in the Royals' locker room as if he'd caught the final out.
Last year he invited everyone to a kegger at his mom's house when the Royals made the Series, its first appearance back since winning it all in 1985. But this year, the boozy throwdown was in the visiting clubhouse at Citi Field in New York.

The players showered Rudd with beer like he was a member of the team.
"I mean, I thought I was going to faint," he told reporters. "I haven't thought about anything. I can't even believe that I'm standing here right now. I don't know how I snuck in."
Rudd has been in attendance at every Royals World Series game in the past two seasons. It has been a long time coming, as the team only had one winning season from 1994 to 2012 before its recent resurgence.
Last year, KC lost the Series to the San Francisco Giants in seven games, but came back and finished the job this season by taking the series 4-1 over the Mets with three late-inning comeback victories.
"It makes no sense,'' Rudd said. "It makes sense that they won because they're incredible. It makes no sense that I'm here right now, celebrating this."
