This basic reprise of Prince Ali was sarcastically sung by Jafar in Aladdin, when he uses his newly gained sorceror powers to expose Aladdin as nothing more than a mere street rat. It was a replacement for the songs 'Humiliate The Boy' and 'Why Me?' after both were rejected as songs for Jafar.
Jafar: Prince Ali, yes it is he, but not as you know him. Read my lips, and come to grips with reality. Yes, meet a blast from your past, whose lies were too good to last. Say hello to your precious Prince Ali!
So, Ali turns out to be merely Aladdin! Just a con, need I go on? Take it from me. His personality flaws give me adequate cause to send him packing on a one-way trip so his prospects take a terminal dip. His assets frozen, the venue chosen is the ends of the Earth! WHOOPEE! So long, ex-Prince ALIIIIIIIIIIIIII! HAHAHAHAAAAAA!!!!!!!
