Let's get real for a second... mannequins are creepy.  Case closed.  

Thankfully though, mannequins do not usually move...until Improv Everywhere's latest flash mob prank proved otherwise.

The improv masters' newest prank involves shoppers and employees at the 5th Avenue Gap in Manhattan -- where all got to experience the nightmarish (what we all thought was impossible) scenario first-hand.

Watch the video below as the store receives some extra mannequins -- and we get to watch some amazing reactions.
