CHiPs

There's a scene where Ponch & Jon go to visit Artie & his friends, hoping to reconcile their differences. They pull up on their motorcycles, park & then proceed to take their helmets off. Ponch, after removing his helmet, leaves it with his bike, setting it on the handlebars. Jon, after removing his, takes it with him. Then the camera cuts to a different angle & Jon is seen removing his helmet yet a second time!
