This is super awesome!
I'm really amused at the fact that she called him a big stupid jerk at the end though. It's just funny what comes out of peoples mouths when they are in a craze from being in shock. It's like...riiiight, so he's a stupid jerk because he proposed to you in a totally unique and sweet way and you are super happy about it.
I know she didn't actually mean it, it is just funny.
