CHICAGO -- What do you do when 5 million fans show up to congratulate you on winning a World Series championship? You take a selfie. That's what David Ross did.

The veteran catcher, who is retiring after this season, took advantage of a moment on the stage during the Cubs' celebration at Grant Park on Friday to take a photo of himself with some of his teammates and the sea of fans packed into Hutchinson Field.

CHICAGO -- President Barack Obama applauded the Cubs' first World Series championship since 1908 by inviting manager Joe Maddon and the team to the White House, while a handful of players will test their comedic chops in a guest appearance on "Saturday Night Live."

Obama tweeted after the Cubs captured the Series by beating the Indians in Game 7.

CHICAGO -- Carl Amrhein has pulled off the near impossible by being both a Cardinals and a Cubs fan during the course of his life.

"I grew up a Cardinals fan," said the retired Amrhein, who was at Grant Park on Friday celebrating the Cubs' first World Series title since 1908 with an estimated 5 million of his closest friends. "Moved up here 30 years ago, and then I changed.

CHICAGO -- The Cubs' World Series win had as much to do with their history as it did with their breathtaking 8-7 win over the Cleveland Indians in Game 7 on Wednesday night, so it would seem only fitting that the now ex-Lovable Losers included the brightest stars from their past to celebrate.

The collective sigh of relief wasn't taken just by the mainstream fanbase, as plenty of former players celebrated the Cubs' historic championship.

CHICAGO -- When Anthony Rizzo caught Kris Bryant's throw across the infield for the final out in the 10th inning of Game 7 of the World Series against the Indians, securing a Cubs win for their first title since 1908, the first baseman tucked the baseball into his back pocket. Rizzo made sure to give that ball to a member of the front-office staff to protect during the wild celebration after the Series win on Wednesday in Cleveland.

On Friday, Rizzo presented that ball to Cubs chairman Tom Ricketts during the team's rally at Grant Park.

CHICAGO -- Dutchie Caray stood on a hill overlooking hundreds of thousands of Cubs fans at Grant Park and Hutchinson Field before the start of Friday's Cubs World Series victory rally and made an observation befitting of the unofficial first lady of Chicago baseball.

"Oh, my god. It's unbelievable. Just look at that crowd out there. My god," said Caray, who was married to broadcasting legend Harry Caray and still plays an active part in the highly successful Harry Caray Restaurant Group at 87.

CHICAGO -- They poured into the city before sunset, coming from all across the Midwest in cars and on buses. Thousands had flown into town on Thursday, from locations as far away as Puerto Rico, Vietnam and China. Those Cub fans lucky enough to wake up in their own beds rolled out of their North Side brownstones without bothering to eat breakfast.

With a chance to join in a communal celebration for their team's biggest win in 108 years, fans started arriving at Grant Park at 5 a.m. CT for a rally scheduled for noon. When the gates opened to let fans enter the park, the dash for spots was as wild as the seventh game of the World Series.

CHICAGO -- It was a blue Friday in Chicago, but it had nothing to do with sadness or any sort of gloomy weather emanating from this great city.

The color was connected to the Chicago Cubs, whose World Series title drew more people to a single event than had ever gathered on U.S. soil.

CHICAGO -- They came by train, by car, by bike and by kayak. They lined the streets around Wrigley Field, Lake Shore Drive and totally overwhelmed downtown Chicago. City officials estimate 5 million Cubs fans, nearly all wearing Cubbie blue and many carrying "W" flags, celebrated the newly crowned World Series champions on Friday.

This party was for all the current Cubs fans giddy after a 103-win club snapped a 108-year drought, and for those who weren't here but helped foster their children's love of the team.

Suddenly, everybody has an opinion on whether Wednesday night's thriller between the Cubs and the Indians slid past those 36 other Game 7s in World Series history to become the greatest ever.

My thought? Well, glad you asked.

The Cubs celebrated their first World Series title in 108 years Friday with a momentous parade and rally culminating at Chicago's Grant Park.

Given the excitement surrounding the Cubs winning their first World Series title since 1908 -- and Chicago's history of celebrating its champions -- turnout for the parade was massive, with city officials putting estimates at 5 million people in attendance. The skies were crystal clear and temperatures were in the upper 50s. Chicago public schools were closed and city officials dyed the Chicago River blue in the Cubs' honor.

Steve Bartman is "overjoyed" that the Cubs won the World Series, according to a report from USA Today, but the longtime Cubs fan did not attend the celebratory parade in Chicago on Friday.

Bartman infamously interfered with Moises Alou attempting to catch a foul popup in the eighth inning of Game 6 of the 2003 National League Championship Series against the Marlins. At the time, the Cubs were leading the series, 3-2, and the game, 3-0, but the play led to the floodgates opening to an eight-run inning for the Marlins, who went on to win Games 6 and 7, and then the World Series.

A party 108 years in the making will take place in Chicago today as the Cubs celebrate the end of a championship drought that spanned more than a century.

Fans who can't make it to Chicago can take in the celebration on MLB Network, whose parade coverage begins at 10 a.m. ET with a special edition of MLB Tonight featuring two live locations at Wrigley Field with hosts Heidi Watney, Jon Paul Morosi and Lauren Shehadi. The event also will be simulcast on MLB.com.

CHICAGO -- If there was a downside to the Cubs' first World Series championship since 1908, it's that they won it on the road, beating the Indians on Wednesday night in Game 7 in Cleveland. Today, the players, manager Joe Maddon and staff will be saluted by their fans in a parade that many Cubs fans probably never thought they'd live to see.

The Cubs brought the team and its fans the franchise's first championship since 1908 with an 8-7 win against the Indians in Game 7 of the World Series on Wednesday night.

As monumental an achievement as it was for the Cubs who won on the field, so many more through the years never got to taste a World Series victory with Chicago. As the city celebrated after Game 7, many of those former Cubs weighed in on this historic moment for the franchise.

It was one of the greatest World Series games ever, and looking back on it, how could it not be? The Cubs' 8-7 victory in 10 innings over the Indians in the deciding Game 7 was seemingly predestined to be a classic.

The Cubs, who hadn't won a World Series since 1908, had fought back from a 3-1 deficit to knot up the Fall Classic. But they faced a daunting Game 7 task on the road at Progressive Field.

Joe Maddon was in charge of the Angels' instructional league program one fall three decades ago when he heard Gene Mauch's gravelly voice behind him.

"I don't know how you're doing it, son," Mauch said. "But you've created a great environment here."

Here are three interesting items from Game 7 of the World Series …

With their 8-7 win in Game 7 of the 2016 Fall Classic on Wednesday, the Cubs' stretch of 107 consecutive seasons without a World Series title came to an end.
