Here's a 1970s, super 8 home movie of family members posing for the camera and noodling around in a garden, likely hamming it up for the camera.  

Clip begins with young family members posing in front of a home garage. They stand next to a motorbike and pose with it. 

Family members stand behind each other, giving the person before him or her a shoulder rub or massage. 

We finally see the family members goofing around in a very green back yard. Again, it seems like they're performing for the camera and the camera person. Then again, perhaps they are inspecting the fruits of all the work they've put in to making the backyard green with growth and quite beautiful, a gardener's dream.
