Yup, it's one way to meet your favorite actor/ actress. I suppose if you're a really good gripper, you could make some decent money and get invited to all the hollywood parties.
In your case, however, being the gripper has it's own benefits.
I think it's the person that holds the microphone way up high during the shooting of a scene. Take a look at the credits next time you watch a flick. You'll notice a whole slew of grippers.
