You know what we all need? Beowulf as a children's story. I listened to this read out at medieval faire last week and it was brilliant with audience participation.

( See Grendel. See Grendel eat. Eat, Grendel, eat. )

How have I never managed to hear about this before? I mean, I've heard about crazy medieval religious dancing and such but a dancing plague? That is a whole new level or crazy and awesome that I scarcely knew existed.
