Nobody spoke of it the first time the song played over the radio in the workout room at one of the local Chicago Fire Departments. The firemen, who take care to keep their body in tip-top shape, are consistently creating workout mixes to motivate each other.

When “Party in the USA” came on over the radio yesterday, however, there was a moment of quiet within the workout area. After an awkward silence, Chief Bryan Jameson simply said, “Who listens to Miley Cyrus?” He and the rest of the men working out scoffed and laughed a bit, all agreeing the song was teeny-bopper crap their daughters listen to.

Nobody, however, made a move to change the song on the mix.

In fact, a one brave firefighter even began singing along. At first under his breath, but once he caught eyes with a collegue who was doing the same, he began to do it a bit more. Eventually, everyone in the weight room was singing “Then a Britney song came on! Yeah a Britney song came on!” and working out significantly harder than they ever had before.

The results were astounding. So many men were motivated by the teenager’s pop song that Chief Jameson has agreed to keep the song on all future workout mixes to continue to have stronger workers.

None of the men actually talk about the day they discovered they all enjoyed listening to that music. There is simply a quiet understanding that when the song comes on, they’re all allowed to go crazy.

Chief Jameson is considering adding Beyonce’s “Single Girls” to the mix, too, though he adamantly denies ever having heard it before. He simply says, “I hear it’s a good song. My daughter told me. That’s all.”
