A Utah police officer pulled off a clever April Fools’ Day prank on an unsuspecting driver who had been pulled over for speeding.

The Salina City officer begins the traffic stop in typical fashion, letting the driver know how fast he had been driving and asking for identification.

Then things get weird.

After the officer claims to have smelled a suspicious odor coming from the vehicle, he informs the driver and the other occupants of the vehicle that he is with the “feline unit.” The officer claims his feline partner, Officer Froo Froo, is certified to detect marijuana, cocaine, heroin and methamphetamine and will meow three times in a row if she detect drugs.

The occupants seem surprised but agree to allow the cat to inspect their vehicle. The officer goes back to his car and brings out a black and white cat, which he then leads through an inspection of the vehicle.

Finally, the officer reveals the whole thing is an April Fools’ Day prank.

The occupants of the car thought it was hilarious and took photos of the officer and the cat.

As for the speeding violation, the officer let the man off with a warning. The officer wanted everyone to know that the prank did not cost taxpayers any money, as he did it on his own time.

Oh, and yes, the officer’s cat really is named Froo Froo.
