I can think of more historical ones to share, but there's 2 of those TV moments that's been stuck in my head since I was a kid. Both centered on one man - Ahmad Rashad.
One is his marriage proposal, on national TV, to Phylicia Allen (Phylicia Rashad, aka Clair Huxtable on the Cosby Show). He did this as a sportscaster on Thanksgiving day in a game between the Lions and Vikings in 1985.

The other is when Rashad made the "Miracle Catch", as a Viking, in the last 14 seconds to beat the Browns in 1980.
