When Oliver Douglas on Green Acres needed a new head gasket for a truck, Mrs. Douglas provided him with something she ordinarily would have thrown in the trash. Namely, the leftover outline of her "hotscakes" as she makes them with a metal lid, like a cookie cutter.

I found this reference on an automotive forum, where all the other users also remembered this episode. They also recalled that Fred Ziffel did some more repurposing by using Lisa's extra hotcakes to shingle his roof.
Such practical people.
she was incredibly beautiful, with skin like heavy cream. I wonder
at the Gabor's beauty regime but they had to have tremedous genes.
