Angel: Are you sure you have no breath? Think it over for a second before you answer. If you need help, just look over there at Spike smoking a cigarette. And while you're working on that one, WHAT IS YOUR LAST NAME?!
Angel, Harmony, and Spike: Guys, you do realize that heating blood in the microwave will ruin it, don't you?
Willow and Tara: Did you two secretly get jobs so that you could pay Buffy rent, or are you both shameless freeloaders?
Hank: You do know that you were legally obligated to provide child support as long as one of your daughters was still a minor, right? Particularly after Joyce died?
Monks: Wasn't it a little risky turning the Key into the Slayer's sister, particularly when the Slayer lives only a few miles away from the spot where Glory needs to complete her ritual? Don't you think it might have been safer to turn the Key into something a bit less conspicuous and/or more difficult to get to? A starling, for instance. Or an angler fish.
