Chris Myers certainly isn't the first nor the last announcer that this will happen to, but the game winning score is the worst possible time to confuse the two teams playing a game in front of you.  As Dallas Clark catches the game winning TD in overtime from Josh Freeman for the Buccaneers against the Panthers, Myers shouts:

"Panthers win!"

*Awkward Pause*

"Bucaaneers win!"

The awkward pause between the wrong call and the right call is always the best part.
