My two favorite are.
My brother and I were watching Monday Night Football. The Bills were taking on the Rams. Jim Kelly was hurt and Frank Reich would be starting. We were told to go to bed at 10. We waited until we were sure our parents were asleep and snuck out into the living room to watch Frank Reich rally the team to a win.
The next was in person with my Father and my Brother. We went to the AFC Championship game against the Chiefs. There was a lot of snow on the ground, it was frigid, and the stadium was electric. A bonus was getting to see Joe Montana play. A really big bonus was seeing him lose to the Bills. Good times.
