What is Thou Shalt Not Deuteronomy?

Ok, so Deuteronomy 1 states "Thou Shalt Not Deuteronomy or I Will Deuter On You Too." If you want to know what happens after that, it says "See Deuteronomy 2". Then it says to proceed on to Deuteronomy 3, 4 & 5 if they want to keep throwing it back and forth with you. Once you reach Deuteronomy 6, just keep on slingin' it until you're out of stock. I can live with that!
