Blood Curdling

We keep hearing about blood-curdling screams and frightening movies that curdle your blood, so I have always wondered: is curdled blood a delicacy for vampires? It probably is, like some kind of blood custard. And to produce this yummy treat, vampires probably have to scare their victims a lot to get their blood to curdle before they bite them. Or, maybe they show horror movie marathons and then have a blood donation drive with nurses in the lobby of the movie theater, so they can get all that especially delicious curdled blood as a special treat. And that's probably the real reason we have Halloween every year: so vampires can get their special curdled blood treat once a year without anyone suspecting what's going on.
