Bengals fans not feelin' Katy Perry

You can play your AC/DC, your Nickelback, your P.O.D., your Papa Roach . . . you can play some really terrible music at NFL stadiums and nobody will say a word.

But Katy Perry? Nuh uh.

The Cincinnati Bengals found out that the hard way, when they played the bubblegum pop star's song, "Roar," before, during and after Monday's win over the Pittsburgh Steelers in Paul Brown Stadium. It was the song to which the Bengals entered the field.

If you're not familiar with it, behold:

Fans erupted, but not in the good way.
