Sometimes it's about the small victories. There's no need to always celebrate huge plays, shattering hits or glorious wins -- a fan should be able to appreciate the little things, like a three-point lead. Or a burrito (?).
Enjoying the game like he's in day two of Burning Man, this dapper chap is heartily enjoying an early lead from a 23-yard field goal. It's the fan to the top right who quickly became tired of his antics, and his claps rapidly became ambivalence.
