When Jafar meets Aladdin in prison to fetch the lamp, he disguises himself as an old man. For some reason, he has his parrot Iago hidden in his back while in disguise.
OLD MAN: There is a cave, boy. A cave of wonders. Filled with treasures beyond your wildest dreams. Treasure enough to impress even your princess, I'd wager.
(The OLD MAN turns his back, and IAGO sticks his head out of JAFAR's "old man" disguise.)
IAGO: Jafar, can ya hurry it up? I'm dyin' in here!
Why was Iago hiding in Jafar's back? Why not just have him wait outside?
