Mayor Bloomberg has made good on his bet with Pittsburgh Mayor Luke Ravenstahl yesterday after the Jets lost to the Steelers in the AFC championship.

Bloomberg unfurled a Steelers “Terrible Towel” at the New York Public Library, then wore a Steelers jersey while assembling CARE packages for military-service members. In order to fulfill the bet, Bloomberg had to post a video of himself with the towel online.

His staff posted the video on YouTube.
