To help promote his new Terminator Genisys movie, Arnold Schwarzenegger took to the streets of Hollywood as Terminator ("Please don't bump my selfie stick" will surely become a new thing) and pranked fans at the Madame Tussauds Wax Museum.
The prank is part of an effort to benefit the charity After-School All Stars, which you can enter over at Omaze.
