“Improv Everywhere” is a group from New York that plans flash-mob stunts and videos the reactions of those passing by!

They mixed things up a bit for Christmas. They rang a door bell with four carolers that quickly turned into an entire CHOIR and 20-person orchestra.

It’s actually pretty awesome and full of holiday cheer…unfortunately once the family went back inside they noticed all of the presents that were under the tree had been stolen…JUST KIDDING!!!!  But for real you have to be careful of scams this time of year.

But for now just watch a crime-free video of a crazy group of carolers!
