New York Mayor Michael Bloomberg has made good on his bet with Pittsburgh's mayor after the New York Jets lost to the Steelers 24-19 in the AFC championship.

Bloomberg unfurled a Steelers "Terrible Towel" at the New York Public Library on Thursday.

Then he wore a Steelers jersey while assembling care packages for service members.

Bloomberg and Ravenstahl made the bet before the Jan. 23 AFC championship game in Pittsburgh.

In order to fulfill the bet, Bloomberg had to post a video of himself with the towel online. His staff posted the video on his YouTube channel.

The "Terrible Towel" was created in 1975 and has served as a potent symbol for Steelers fans.

The Steelers play the Green Bay Packers in the Super Bowl on Sunday.
