timprov and I stayed up too late one of the nights this week and came up with clap-clap jokes. What, you may sensibly ask, is a clap-clap joke? It's a knock-knock joke, but in Dragaera. Also, if you're feeling less Vlad-ish and more Paarfi-ish, you may respond, "To whom do I have the honor of speaking?" or "Whom do I have the honor of addressing?" rather than, "Who's there?"
( if that didn't make any sense to you, you probably don't care what's under the cut )
