FM & AM
Original 1972 album liner notes
Nixon is soft on fascism. The gross national product is gross. Elephantitis does not improve the memory. Mothers’ milk leads to heroin. If you break a crumb in half, you have two crumbs. When stepping on the brake, your life is in your foot’s hands. The U.S. Plywood building is made of steel and stone. There are no two dandruff flakes alike. Beer nuts is the official disease of Milwaukee. Everyone over 110 is out of work. Rose Kennedy wears a natural. Give a Shriner a shiner. Recycle confetti. No two ways about it, there are two sides to every story. Edgar Cayce was not a medium, he was an extra-large. The Vatican Police speak pig Latin.

Coptic - the language of the Copts, which represents the final stage of ancient Egyptian. It now survives only as the liturgical language of the Coptic Church.
Just in case someone else didn’t get it, I’ll save you the google.
