See what happens when this UFC game developer tries to play a prank on UFC Heavyweight Frank Mir!

Frank Mir is possibly one of the most dangerous men walking the planet today.

His bone-crushing submission wins over Antônio Rodrigo Nogueira and Tim Sylvia have cemented him as one of the greatest heavyweight submission artists of all time but his knockouts of Mirko Filipović, Todd Duffee, and Antônio Silva remind us that he is a threat everywhere.

Making him one of the last people on earth that you’d want to upset or get on the bad side of.

The game developer in the video below must not of gotten that message as he tries toprank Frank regardless. But little did the developer know that his buddies let Frank know what was going to happen ahead of time.

Which allowed for someone to stand off to the side to record the incident for us all to enjoy.

The developer begins directing Mir through a motion capture test that is actually just the hokey pokey. It doesn’t take long for Mir to catch on, approaching the developer forcing him to backpedal surely beginning regretting what he’d gotten himself into.

But it is all in good fun and Mir can only keep a straight face for so long before the room erupts with laughter and the tension ends.

The moral of this story is pretty simple. It’s a really bad idea to try and play a prank on Frank Mir, you just don’t mess with a Heavyweight, especially Frank Mir..
