The Kansas City Chiefs beat the Buffalo Bills in a roller coaster of a playoff game on Sunday. The final was a 42-36 overtime score.

Chiefs fans celebrated with good reason, but certainly did not dance on the hearts of Bills Mafia at all. Instead the supporters known as “Chiefs Kingdom” did exactly what their foes would have probably done.

Following the crushing loss for the Bills, the Patricia Allen Fund named for the late grandmother of Buffalo QB Josh Allen which benefits the John R. Oishei Children’s Hospital of Buffalo, started receive donations. Considering the circumstances, numerous ended up coming in from the Kansas City area in $13 increments.

As the story went on the field, the Chiefs took the final 13 seconds of the contest to rally and win in extra time. That’s where the figure comes from and it came from a good place.

According to the Buffalo News, a Kansas City fan who runs “Chiefs Kingdom Memes” on social media named Brett Fitzgerald came up with the idea.
