- The title Tomorrow We Diet is a pun on the expression, "Let us eat and drink; for tomorrow we die." It is found in 1 Corinthians 15:32 in the Bible, often misquoted as "Eat, drink, and be merry, for tomorrow we die," which is parodied in the end as "Eat, drink, and be merry, and tomorrow we diet."
