In fact, they've already made history, as the first team with back-to-back Super Bowls to reach the Super Bowl for a third-straight time. (All the others lost in the conference championships.) Fortunately, the Chiefs absolutely own the Bills in the ~~Arrowhead Invitational~~ AFC Championship game.
For my part, I will never forget parking cars for three hours in the cold as a kid in the 90's to watch the kicker who shall not be named piss away my team's chance at a Super Bowl against the Colts in 1996. Back then you couldn't get a seat, so the only way for a poor kid to get into the stadium was parking cars. They paid you with an SRO ticket, and it was pretty cool, given that this was the time when Neil Smith and Derrick Thomas were wrecking QB's.
