Forget the light-up Christmas sweaters.
Former Bears legend Jim McMahon had some unexpected advice for quarterback Mitch Trubisky during the team's 100th anniversary celebration over the weekend.
The team's last two Pro Bowl quarterbacks got together onstage during a panel at the star-studded event at the Donald E. Stephens Convention Center in Rosemont.
That's when McMahon decided to give the young star a little advice.
"To be successful, you've got to start wearing a headband and some sunglasses," McMahon said.
Trubisky promptly put on a headband while saying "Step one." Then, he put on some shades.
"Now you're ready to go kid," McMahon said during the exchange.
It wasn't the only note-worthy moment to come out of the days-long event.
Six Hall of Famers and 230 past and present players and coaches were on hand as the Bears kicked off their 100th anniversary celebration weekend on Friday.
When Gale Sayers was wheeled onto the stage, the roar from the crowd could have drowned out the jets at nearby O'Hare International Airport.
Sayers has been weakened by dementia, which was diagnosed five years ago. But the 76-year-old still made the 130-mile trip from his home in Wakarusa, Indiana.
Sayers showed up wearing his gold Hall of Fame jacket and a blue and white cap with the number 40. He wiped his left eye as his old teammate Dick Butkus, Dan Hampton and Richard Dent stood clapping onstage.
Moments later, Mike Singletary came out. And with Mike Ditka also there, the Bears had six Hall of Famers onstage at once.
Ditka said he was glad to be part of the festivities. The Hall of Fame tight end and iconic coach of the 1985 Super Bowl champion Bears had a heart attack on a golf course in November.
Gary Fencik, the two-time Pro Bowl safety who played on the Super Bowl championship team, said the event is special. He's from Chicago and holds Bears season tickets.
"You don't really think about that you're part of the history of any organization," he said. "It's not that I haven't read about the Bears' history or the NFL. But this gets you a little more focused on that — and that you are a part of a very important fabric to the city and the NFL."
McMahon, the "Punky QB" on the '85 team, called Chicago "a special place."
"I've always loved this town, lived here for 28 years — almost half my life," he said. "All my kids were born and raised here. It's a special place. And this was a special team that I was involved with."
