This GIF symbolizes the enigma that is Kansas City Chiefs football. More from Deadspin:So the refs screwed up, gave the Chiefs a touchdown they shouldn't have gotten, thus providing the opportunity to excessively celebrate and earn a 15-yard penalty, only to have review determine that it was not in fact a fumble and therefore not a touchdown. As a result of the incomplete pass, the Steelers were awarded a first down. Because of the unsportsmanlike conduct of excessively celebrating a touchdown that did not technically happen.To make matters worse, the Chiefs ultimately lost the game in overtime in heart-breaking fashion. Chiefs quarterback Matt Cassel threw an interception in extra time that was returned all the way down to the five-yard line. The Steelers subsequently kicked a game-winning field goal and the rest is history. Final score: PIT 16, KC 13. Kansas City fell to a league-worst 1-8 on the campaign while the Steelers improved to 6-3.
