Bill Murray never gave up hope!

The world may have rejoiced now that the Chicago Cubs won the Major League Baseball World Series for the first time 108 years -- but no one was happier than superfan Bill Murray, who remained a loyal optimist for decades.

The beloved actor, who has been a frequent visitor to Wrigley Field and a longtime supporter of the cubbies, got to go in the team's locker room after the epic win -- and it was good stuff. Murray is like a kid in a candy store in this video!

While in the locker room, the Ghostbusters star clinked champagne bottles with center fielder Dexter Fowler, and even got sprayed with a champagne bottle by Cubs president Theo Epstein.

Murray told CSN Chicago, “I never panicked. Of course I thought it was going to happen." Yeah, you did!

A loyal fan his whole life, Murray looks like he had a grand old time last night -- and so do the rest of the cubs!
