For their latest prank, NYC flashmob collective Improv Everywhere invaded Manhattan's 5th Avenue Gap store, wearing white morphsuits under their Gap clothes, and tried to blend in with the store's regular mannequins.
Customers were surprised and delighted, and store employees had to give the improv-ers credit for their convincing outfits. But they also called police, who showed up and placed several of the (human) mannequins in handcuffs.
After detaining them for a little while, officers decided there was no harm done and let them go. Nobody was banned from the Gap.
