With most prank videos, it's pretty easy once the prank gets started to figure out how it's going to end. In this mannequin flash mob prank, the end was something even I was shocked to see happen.

Obviously, someone didn't get the prank, because they made a call that completely changed the expected outcome of this weird, but funny prank. The person who set this up has done pranks before and even he was surprised at how the prank ended.

Based on the post prank interviews with the participants, this ended up something much different than they expected. After it was all over, it was nice to see they still saw it as an unexpected, yet fun, experience.
