1994: The United Center opened with a ribbon-cutting ceremony followed by a $1,000-a-plate black-tie gala. Inside, the guests danced to the Dick Judson Orchestra. Outside, nearly 1,000 demonstrators demanded more jobs and contracts for the Democratic National Convention to be held there two years later.

The first event open to the public came 11 days later, and it wasn’t a Chicago Bulls or a Chicago Blackhawks game. It was the WWE’s stars Bret “Hit Man” Hart, Lex Luger and the Undertaker mixing it up.

“Breaking the seal on this dolled-up barn was not the Rolling Stones, as originally rumored, but rather the sophisticated artistry of the World Wrestling Federation’s SummerSlam ’94,” the Tribune reported. “If the faux action in the center ring became tedious, seated patrons could bide their time counting United Airlines logos and listening for the opening strains of Gershwin’s ‘Rhapsody in Blue’ every time a cash register drawer opened.”

2018: Sister Mary Jo Sobieck threw a ceremonial first pitch for a perfect strike at Rate Field after bouncing the ball off her bicep. Then a teacher at Marian Catholic in Chicago Heights, Sobieck’s pitch was captured on a baseball card, a bobblehead and was even nominated for an ESPY Award.
