A guy in Poland named Sylwester Wardega posts prank videos on YouTube, and has about three million subscribers.  He's the guy who did the spider-dog video last year that's gotten over 143 million views.  And for his newest one, he had two people dress up in velociraptor suits, and scare Chris Pratt, star of "Jurassic World."  Apparently his people were in on it, but Chris had no idea.
