The Argonauts and the Stampeders aren't the only ones with bragging rights on the line in the upcoming Grey Cup championship.

The mayors of Toronto and Calgary, the two teams' respective hometowns — are also getting in on the action.

Calgary Mayor Naheed Nenshi has proposed a friendly wager that would see the losing city's mayor donating his weight in food to the winning city's food bank.

The loser would also have to wear the winning team's jersey for a council meeting.

Nenshi issued the challenge to Toronto Mayor Rob Ford on Twitter.

Hours later, Ford tweeted his acceptance, adding the Calgary mayor would "look great in Argo blue!"

The 100th Grey Cup is being held in Toronto on Sunday at the Rogers Centre, the Argos' home field.
