What is a part of NFL history have you been a part of or witnessed? (idea from askreddit)

I'll start. This is a weird one. I saw Brett Favre's very first NFL action in the NFL. It was 1991 in Washington and he was 0-4 with 2 interceptions.

Then 14 years later I saw Aaron Rodgers first NFL action. It was in Baltimore and I'm pretty sure he fumbled his first snap. In the end he did better than Favre. Both games were major blowouts.
