Charles Barkley said that.
And I would have to go with the whole Arizona Cardinals game. I remember I kept my composure untill about the beginning of the 3rd where Rex through another pick. I gave up on them, and then Mark Anderson sacks Lienart and then Urlacher made Edge fumble and finally Devin Hester's return. Even then, the Cardinals still had a chance to win the game but Rackers missed the fieldgoal. The single most greatest comeback I have ever witnessed in my lifetime.
