Revealing mistake: When Gazeem is standing in front of the Cave of Wonders, he leaves no footprints in the sand.

Continuity mistake: When Jafar is holding the Sultan and Jasmine captive, Jasmine is wearing a gold band round one arm. As Jafar pushes her to the floor, it has switched to the other.

Trivia: When the Sultan is idly building a tower of miniature animal figures, one of the figuresĀ is the Beast from Beauty and the Beast. Also, the king crab the genie pulls out of his cookbook is Sebastian from The Little Mermaid.
Answer: Aladdin is referring to the person riding the horse as being a "horse's ass" in the way he is acting, thus the horse the person was riding on has two rear ends, his own and the rider.
