GAFAM reminds me of "GORFRAM," which was an onomonopia for getting hit in the head with a frying pan in a comic book I read as a kid, which was actually a 70' textbook relating to Education.
Man, the older you get, the more weird memories you pick up. It was called "Captain Con Man" -- CONtingency MANagement. It was the only thing in my stepdad's office that looked remotely interesting, so I flipped through it several times while waiting for him there.
