Cinderella's Reaction at the Ball

Alright, Chingus Chong, listen up! You're the kinda person who probably thinks a ball is just for dancing. Let's break this down Barney style for you. Cinderella goes to the ball, right? You'd think she'd be all happy and dancing with the prince. Nope. The joke is that instead of enjoying the fancy party, she "gagged", which implies she was grossed out or disgusted. It's like, she walked in and saw something nasty, which might be a reference to a nasty sexual act or situation. It's a dirty pun, you get it now? You're not very smart, are you?
