Calgary Mayor Naheed Nenshi is feeling blue about wearing white and blue.

Nenshi sheepishly showed up Tuesday for city council budget talks sporting a Toronto Argonauts jersey with his name emblazoned on the back.

On Monday, he went to work in his red Calgary Stampeders sweater, saying he needed time to mourn after the team's Grey Cup loss to the Argos on Sunday.

Nenshi had made a wager with Toronto Mayor Rob Ford over the game and must also donate his weight in food to the Toronto Food Bank.

Nenshi said he planned to honour the bet despite Ford's removal from office.

A judge ruled Monday that Ford violated the city's conflict of interest rules but Ford is appealing the decision.
