Why is it every little girl's favorite fantasy?

"Be mine forever and then pick up after me when we get home, bear me 5 kids and raise em, cook me 3 meals a day (make sure they're warm), wash and press my clothes, oh, what the heck. I really meant- be my slave forever..."

Did that just ruin the photo?
Yeah, sorry about that.
I love weddings. Honest, i really do.

I just wanna know... what made it so damn important for all of us?
