Mayor Naheed Nenshi is asking Calgarians to help him and Vancouver Mayor Gregor Robertson work out the perfect playoff wager.

Help me and <a href="https://twitter.com/MayorGregor">@MayorGregor</a> out with the terms of our playoff bet. Since <a href="https://twitter.com/NHLFlames">@NHLFlames</a> will win, what do I want from Vancouver? —@nenshi

This isn't the first time Nenshi has initiated a friendly bet between mayors:

<a href="https://twitter.com/nenshi">@nenshi</a> <a href="https://twitter.com/MayorGregor">@MayorGregor</a> <a href="https://twitter.com/NHLFlames">@NHLFlames</a> how about the loser sends lunch to the winner. (fresh seafood vs Alberta beef) :) —@calgaryrants

<a href="https://twitter.com/calgaryrants">@calgaryrants</a> <a href="https://twitter.com/MayorGregor">@MayorGregor</a> <a href="https://twitter.com/NHLFlames">@NHLFlames</a> except I don't love salmon and he doesn't eat beef. —@nenshi

With hundreds of suggestions flooding in on Twitter, it could be tough for Nenshi and Robertson to work out the terms of the bet.

<a href="https://twitter.com/CBCScott">@CBCScott</a> if we win <a href="https://twitter.com/MayorGregor">@MayorGregor</a> has to ride a bull the the stampede. If the Canucks win <a href="https://twitter.com/nenshi">@nenshi</a> has to ride a salmon up the coast to N.Van —@mibergeron

The two mayors will have to work out the terms of the bet soon, as the Calgary Flames take on the Vancouver Canucks in the first round of the playoffs Wednesday night.
