They're not betting locally made foods, as politicians typically do.
Instead, the bet between Illinois Gov. Pat Quinn and Massachusetts Gov. Deval Patrick over the Stanley Cup series is volunteering at food banks in each other's state.
A wager also is reportedly in the works between the Chicago and Boston mayors over the series, which begin Wednesday night in Chicago.
For the governors' bet, if the Chicago Blackhawks win the cup, Patrick will fly to Chicago and volunteer at the Greater Chicago Food Depository. If the Bruins win, Quinn will head east and volunteer at the Greater Boston Food Bank.
"Gov. Patrick is skating on thin ice by betting against the mighty Chicago Blackhawks," Quinn said in a statement. "But the Greater Chicago Food Depository can always use extra help, so after he works a shift there, I'm happy to take Gov. Patrick to the United Center to see the Stanley Cup return home."
Patrick talked smack about the Blackhawks, too.
"I look forward to seeing the Bruins circle the ice with the Stanley Cup above their heads," Patrick said in a statement.
Quinn and Patrick, a south-side Chicago native, are friends and a portion of Wabash Avenue near 53rd Street was recently named Honorary Deval Patrick Way.
The Chicago Blackhawks have won four Stanley Cup championships, the most recent in 2010. The Boston Bruins have won the Cup six times, most recently in 2011.
