What happens when you get Arnold Schwarzenegger suited up as a battle-scarred T-800 and unleash him upon a crowd of unsuspecting Hollywood tourists? 

Well... you get magic. As evidenced by the video below, put together by Arnold to benefit after-school programs. He's offering one person the chance to join him at the premiere of Terminator Genisys, and in doing so decided to prank folks in a wax museum and mingle amongst Hollywood's costumed performers.

Check it out...

We're absolutely loving the "I'll be back" quote-down that goes on between Arnold and another guy dressed as the Terminator, but our favorite part might be the couple seconds we see of Arnold in the makeup chair, humming the Terminator score as if using it to get into character. We want to imagine he does that whenever he suits up -- well, that, and he grabs his selfie stick.

Terminator Genisys hits theaters on July 1.
