Open Season Easter Egg - "It's (a) Donkey!"

At the part where Elliot is running away and sneaks backstage Boog's show, Elliot ends up getting pushed on stage. When the camera angle change to the stage, you can hear a woman shout "It's a donkey!" This is a reference to Shrek, a movie made by the same studio as Open Season (Dreamworks). If you're familiar with Dreamworks' movies, then you probably know that in a lot of their animated movies they have a character like Boog or Shrek and a character like Elliot and Donkey. Elliot is the same type of character as Donkey.
