Listen, Jack, here's the deal: God called Moses from a burning bush, and said, "C'mon, man, I want you to go to Pharaoh and tell him to let my people go!" My father used to say, "You gotta do what God says!" and Moses was like, "Excuse me, God, why me?" and God said, "Literally, I'm gonna be with you, and I'm not joking - I'm gonna give you a sign!" So Moses went back to Pharaoh and said, "See here, Jack! God wants you to let his people go!" and Pharaoh was like, "What was that? No malarkey! Not gonna happen!" But God gave Moses some more signs, and Pharaoh still said, "No way!" So God sent some plagues down on Egypt, and Pharaoh was still like, "Nope!" But then God sent the last plague, and Pharaoh was like, "I tell you what - let 'em go!" So the Israelites went, and God said, "Or uh, you know - don't forget the Sabbath!" And then Moses and the people went on their way.
