You know Dasher and Dancer and Prancer and Vixen, Comet and Cupid and Donner and Blitzen.

But do you recall the most felonious reindeer of all?

That's Rudolph, as he - make that she - was caught on camera robbing a store in Fort Collins, Colorado.

Santa's helper turned out to be a real Grinch, as the thief under the reindeer mask was filmed burgling a business.

Let it be known that Fort Collins' finest have a sense of humor, because police uploaded security footage of the festive robbery (which took place last week) with a banjo cover of "Santa Claus is Coming to Town" playing in the background.

They even included new lyrics to the classic "Rudolph" song, rewritten for the reindeer's rebellious phase:

Rudolph the Red Nosed Burglar / Had a very shady scheme / And if you saw the video / It would want to make you scream.

All of the other burglars / Used to steal without disguise / They weren't like this Rudolph / She's different from the other guys.

On one foggy December eve / Rudolph came to steal. / Broke into a Hickory shop, / Never expected to see a cop.

Oh how the camera caught her / As she committed burglary / Rudolph the Red Nosed Criminal / We need your help with her I.D.

Police asked anyone with information about the robbery to come forward, "so we can notify St. Nick."

Despite getting into the festive spirit with her clever mask, at one point the suspect actually pulled it off and gave the camera a good look at her face. That means the odds are good that she'll spend Christmas behind bars.

Whether she was trying to sneak an early look at her Christmas presents, or just making off with some stolen goods, we hope the woman in this video doesn't mind finding a lump of coal in her stocking on Christmas Day.
