Ellen DeGeneres pranks her colleagues with backstage scare

Ellen DeGeneres is well-known for pranking not only her celebrity guests on The Ellen DeGeneres Show, but also her colleagues — most of all her producer Andy Lassner.

It appears as though with Halloween passing just last week, DeGeneres took the opportunity to spook her co-workers backstage with a jump scare that worked on everyone who was unlucky enough to be walking by.

Well... almost everyone.

A video posted to The Ellen Show's Instagram account shows many producers and others working backstage on the talk show walking by a large box which appeared to be empty.

However, once they walked past, someone in a monster masks with a wild wig popped out of the box screaming, terrifying anyone they came into contact with.

Ellen wrote beside the video, "Halloween is a little different this year, but I still found a way to scare everyone... except @sir_twitch_a lot."

This appeared to work for all of Ellen's colleagues, until finally we saw DJ tWitch, who had clearly gotten wind of the Halloween prank, crawl up besides the box on the floor and wait for the prankster to jump out of the box.

Once this happened, he himself popped out and in turn scared the monster-suited person, laughing and clapping his hands together with glee when he pulled it off.

In a comment on the video, tWitch himself commented, "Paranoia pays off sometimes," with a laughing emoji.

You can see the hilarious prank pulled off above, and keep watching for tWitch's brilliant revenge plot.
