In the middle of Pharaoh's song about his dreams, he asks Joseph (Donny Osmond) to tell him what it means. Joseph says, "Well, I understand the bit about the corn...but I'm not so sure about the cows." After a little more speaking, Pharaoh proceeds to repeat his dream about the corn. Didn't Joseph already understand that part?
Kind of surprising that the mistake made it past the editing room!
