Got this the other day from a friend of mine, and have spent much time laughing over it.
These are a couple of pages from the conductor's score of "Faerie's Aire and Death Waltz" - and it's inherently (and deliberately) unplayable. If you have any experience at all reading music - or even if you don't - take a look at the graphics and have a number of good laughs.
To give you a taste: here's a thumbnail of the top lines of both pages. Click on the pictures to download the full versions.
Page 2 (Note: Now rumored Apocryphal):
(Oops - sorry, lost to the ether. Currently searching for new copy)
"Faerie's Aire and Death Waltz" was "composed" by John Stump.
Oh, yes, and it's "Based on a Cro-Magnon skinning chant."
UPDATE: You can also purchase professional, sturday, 11 X 17 laminated copies by emailing a request to firstname.lastname@example.org. According to distributer Tom Hall, these laminated sheets, when held firmly between the fingers and waved in the air, make a most wonderful "woop - woop - woop" sound. Wow! That has always signified fine quality music to me ;)
