A couple of auto mechanics are working when one of them bites into a Slim Jim, notices some grease on the other guy's fingers and sees an opportunity to have a little fun. He signals to his buddy that there’s something on his face. The unsuspecting friend goes to wipe it off, leaving a black streak across his cheek. His buddy keeps gesturing that he hasn’t quite gotten it, so he keeps wiping his face with his finger. This continues back and forth until he’s left with whiskers and a black nose from grease. The friend thanks him, but before he walks away, his friend dangles keys and gets him to swat at them like a cat. As he walks away to greet a customer, his boss gives him a cat-like growl. The spot ends with the iconic campaign line: "Snap into a Slim Jim."
