What were they?
Mine were...
1. Beating Dallas on MNF in 1980 38-14. Being up 38-0 and hearing Frank Gifford say "if you're just tuning in, this really is happening to the Dallas Cowboys" was an awesome feeling. Of course, two weeks later we lost at Dallas in the playoffs, but for one night this was the best feeling ever.
2. Beating New Orleans in the Flipper Anderson game (sometime in the 80s). The Saints had beaten us at our place that season and John Robinson put his foot in his mouth by saying "we basically forfeited that game." The Saints led big late in the game and their fans were chanting "For-feit! For-feit!" But Flipper was unstoppable and we won in overtime. Pretty sure Kevin Greene had a huge play to set up the win, too.
3. Beating Seattle in 1979 24-0 and holding the Seahawks to negative seven yards of offense. That still boggles my mind.
