Charlie: I'm gonna need a best man, someone I totally trust.
Bailey: Best man. Charlie, don't do it, don't do that. I'll drive you nuts. We'll be at each other's throats.
Charlie: Bailey, listen to me, I know what I want, all right. I want the perfect wedding. I want to walk down that aisle and I want to know someone who cares, like, way too much made sure that there's not one doily out of place. Now, who else can give me that besides you?
