Published in 1981, Miss Piggy's Guide to Life shares a shelf in our reference library with Fountain Head, Architectural Graphic Standards Illustrated, and the Steve Jobs' Biography. It's just that essential.
On page 102, we see Miss Piggy's costuming for the consummate "Underground" Restaurant Critic.
"Continually shifting garment repertoire with the accent on clever disguises (the need for a steady development of new ruses ensures great latitude for experimentation with novel styles); lunch is the occupation; since restaurants are the workplace, surroundings vary from dingy basement munch-hovels with waxy wine bottles and electrified pictures of the Bay of Naples on velvet to chic bistros with tasteful appointments."
Lunch is the occupation. Words we absolutely live by.
