A bet's a bet.
New York City Mayor Bill de Blasio engaged in a friendly bet with Kansas City Mayor Sly James prior to the 2015 World Series, which he lost when the Royals defeated the Mets in five games.
De Blasio's punishment came in the form of singing "Kansas City" with some support from the American Ballet Theatre.
Despite his best efforts, the head honcho of N.Y. didn't do song creators Jerry Leiber and Mike Stoller's catchy tune any justice.
