“It’s entropy, man!”

 I wrote, “It’s  entropy, man” in the post below with a feeling I was quoting—but whom? I thought maybe Bill & Ted, but when I googled it, Flanders & Swann came up (a more erudite Bill & Ted?) —specifically their comic song “The First and Second Law of Thermodynamics” (1964). The line comes at the end, after—snap your fingers— “Heat cannot of itself pass/ from one body to a hotter body…” https://youtu.be/VnbiVw_1FNs

F&S are little known here in the US, though, and I doubt I heard it from them. I think I made it up based on Dick Shawn’s groovy character in The Producers (1967), Lorenzo St. DuBois, LSD to his friends.
