Grace and Frankie is a Netflix original starring a few older stars, call it a tetrafart cast covering Lily Tomlin's nature, San Fran, yoga, chanting, and offspring in CA upscale, Jane Fonda's aging cover girl image (think Barbarella went professional), and more. I liked the few episodes I've viewed, but most of my music posted on the Bluegrass thread that rs and I have kept running, (thanks rs- I like it all) most of those artists have died or are old farts too. Anyhow, whether it's funny only to old farts or not is a question I cannot answer.
Tomlin's old hippy is rotfl for me. Their adult kids have witty dialogue too.
