Remember the classic twin sister in the mirror prank? Patrons of a women’s restroom were shocked and horrified when they went to use the mirror only to find they had no reflection. Yet the woman adjacent to them did!

Really there was no mirror, only a sheet of glass separating a duplicate room. The woman actually had her twin sister copying her every move to make it appear as if she was in front of a mirror. 

To promote the new Last Exorcism Part II, the movie studio created this undercover commercial using a similar prank technique. This time, women at the salon were terrified to see a ghost monster appear only momentarily in the mirror in front of them while getting their hair cut. 

Naturally, they freaked out. 

Now, the new viral advert, titled Beauty Salon Scare, has already garnered over 120,000 hits
