Arnold Schwarzenegger put on a fake black ponytail, black mustache and a baseball cap and hit a Gold's gym in Venice, Calif., to give pointers to random members.
"Hi, how's it going? How many miles you running?" he asks one woman on a treadmill. She stops, looks at him, takes out her ear buds and says, "Oh my God. Hi."
After all, it's pretty tough to disguise Arnold.
Schwarzenegger did the video (which debuted Tuesday) to raise awareness and money for the After-School All-Stars, a nationwide program that provides free mentorship, homework help, tutoring and activities to students from low-income families.
One guy laughs and says, "Come on, Arnold." Schwarzenegger replies, "My name is Howard."
But not everyone recognizes the star. A woman looks at him as she lifts weights, and says, "You look so familiar to me!"
He says, "Maybe you've seen me on an FBI Most Wanted list."
Donors who give at least $10 to the organization through omaze.com (the same site that's offering $10 tickets for a date with George Clooney) will be entered for a chance to win two tickets to Los Angeles, for an "experience" that includes riding with Schwarzenegger in his personal Sherman Tank and smoke cigars.
He's also matching every dollar donated.
