Mitchell Trubisky, the starting quarterback for the Chicago Bears, had a solid season, leading his team to a 12-4 record and its first division title since 2010. To show his appreciation, Federico Prian, a 24-year-old Chicago native, started sending Trubisky $8 — roughly the cost of a beer — on Venmo for each win.

"I'll buy my friends a beer to be nice, so I'll send Mitch a beer any day," Prian told CNBC in December, prior to the Bears' playoff loss last week to the Philadelphia Eagles. "My dream would be for him to thank me and say I kept him going."
