This is exactly what the headline says it is:
Jaxson de Ville, the wonderful Jacksonville Jaguars mascot, made a bet with the Seahawks mascot on Sunday's game. Whether Jaxson was given the points or not didn't matter: He lost, and lost fairly spectacularly. But it did lead to the video above and these moments forever preserved in GIF form:
The Jaguars might be the worst team in the NFL this season, but they have the greatest mascot. And it's really not even close.
