It's only a mistake if they let themselves be flummoxed by these occurrences.
Use it as an opportunity to gradually phase out of 'halftime shows' altogether. Just replace it with a montage of significant plays and stats accrued in the first two quarters plus commentators discussing them, put on a very short documentary about stuff in the NFL's history, have old Hall of Famers with a beef with each other argue on air, or what the heck, even try comparing the game with the inevitable simulation done on the latest Madden. Let it be anything that's at least related to football.
That's what Super Bowl viewers should be getting. Instead we get men screeching into mics and women shaking their asses. It's a disgrace.
Let the halftime be about football as well, I don't want anything else if I'm watching the SB. Hell, just fill the halftime slot full with commercials if you like money that much, NFL, at least the SB gives us opportunities to watch some novel, funny ones.
the Super Bowl isn't about football it's about money
