In person? Would have to look at the schedules back in the day, but two games stand out. One was against Hawaii, and I remember we gave up a safety. Later in the game, we had them pinned deep, made a stop, and some Vols picked up the Hawaii player, lifted him over their heads, and carried him in the end zone. Refs didn't buy it.
Other game was the Larry Seivers two point catch against Clemson. My dad ALWAYS wanted to leave early, beat the traffic, and we missed the comeback. Dad is now 85, and bless him, I STILL give him a hard time about leaving early from that game!
