There are some songs that come on the radio when you're driving that just force you to clap and sing along with.
Taylor Swift's Shake It Off is one such culprit, forcing us to even do the girly hand-flick thing as well.
That's all well and good if you're just a regular dude, but when you're a cop, it's downright hilarious.
This local cop knows what we're talking about, when he recorded this brilliant lip-sync of Shake It Off in his cruiser.
Excellent hand-flicking, Mr. Policeman.
