In order to promote a charity raffle that he’s involved in, Arnold Schwarzenegger recently took to the streets of Hollywood Boulevard dressed up as the Terminator.

After posing with fans, meeting another Terminator in the wild (although the imposter wasn’t even as good of an Arnold imitator as J.J. Watt) and uttering the unbearably funny line “Please don’t bump my selfie stick,” Arnold made his way to Madame Tussaud’s where he scared unsuspecting visitors with his perfectly robotic visage.

The whole spectacle was definitely entertaining but Schwarzenegger wasn’t just doing it just for the fun of scaring strangers. The prank was done to raise awareness for a charity raffle benefitting the After-School All-Stars.

Entries will support the After-School All-Stars program and one lucky winner will get to take a friend and attend the Terminator: Genisys premiere with Arnold himself.
