Now it's getting serious.
Mayor Bloomberg and Pittsburgh Mayor Luke Ravenstahl have staked the image of a landmark from each city on this Sunday's Jets Steelers faceoff.
In this mayor-to-mayor wager, Ravenstahl must put a Jets "fireman hat" on a Pittsburgh landmark and post a video of this sight on YouTube if Gang Green triumphs.
But if the Steelers win, Bloomberg must video himself hanging a Steelers "terrible towel" on a New York landmark and post the footage online.
The losing mayor must also wear the jersey of the winning team while participating in a project to assemble care packages for armed services members who have recently returned home.
