All of the designated drivers don't mind sticking to the fizzy juice all night because it's hilarious watching people when they're drunk. They also relish in the fact that they can then tell you everything that you did from the night before on the morning after. This includes all of the scandalous details from who you tried to get with to the lollipop that you tried to steal from the bathroom. Don't ever try to steal anything from the bathroom because they will find you and they will get you.
