Even surly Stormtroopers need to kick back once in a while.

If you've ever wondered what the soldiers of the dark side do when they're not busy battling those pesky rebels, you'll find the answer below. Apparently, on their days off, they like nothing more than to head over to Dublin, engage in a spot of street dancing and then head straight to the nearest pub.

On Wednesday, Instagram sightings of Stormtroopers in Ireland's capital city reached an all-time high.

What Darth Vader would make of this doesn't bear thinking about.

After what must have been an exceptionally sweaty dance, the group made their way to a local pub.

It's unclear exactly why the Stormtroopers decided to organise this impromptu dance party, but if we had to guess, we'd say it was probably the work of a local flashmob group.

Hey, Stormtroopers need to have fun too, you know.
