CHICAGO -- The Chicago Cubs on Saturday, October 22nd won the National League championship to advance to the World Series for the first time in 71 years.



Many still-stunned fans took to social media Sunday morning to ask if they'd been dreaming and to catch up on the posts from famous Cubs fans.



Comedian and actor Bob Newhart posted a photo of himself, his grandchildren and the "W'' flag they made for him.



Actor John Cusack posted two words last night along with a photo of the team celebrating at Wrigley Field. As he put it: "It's. Done."



Chicago Mayor Rahm Emanuel issued a statement Saturday night celebrating the pennant win. He says: "The fun continues in Cleveland on Tuesday night."



Large crowds of people hit the streets outside Wrigley Field on Saturday night after the Cubs beat the Los Angeles Dodgers in Game 6 of the NL Championship Series and advanced to the World Series for the first time since 1945.



The excitement over the Cubs victory has fans calling for a very special guest broadcaster during the World Series.



A petition has been created to replace FOX's Joe Buck with Milwaukee's Bob Uecker.



That petition is posted at Change.org and more than 52,000 people have signed it -- calling Uecker a "national treasure."



Fans want Uecker in part because he played a broadcaster for the Indians in the hit movie "Major League."









The Cubs face the Cleveland Indians in Game 1 on Tuesday.
