At college, they always had an event during finals week each semester, to help students let off excess stress. It was aptly named "Primal Scream", and that's what people did. They'd build a bonfire by the Fence (a CMU landmark, of sorts), make some food, and students would gather around and scream until their finals stress was gone.
I think it's a good concept to revive around now. =)
One, two, three... *scream*.
I certainly feel better now--do you? =)
