Flying Hedgehogs

[meglet2]

Can anyone give me a reference number for Alexander's post in which 
he introduced the Russian saying about the paranoid searching the 
trees for flying hedgehogs? Believe it or not I want to quote it in 
an essay on state repression in Latin America (long story - email me 
off line if you're interested) and the Yahoo search engine 
absolutely refuses to admit to any reference to every varation of 
flying hedgehogs that I can think of, including Eloise's OOTFH. Very 
frustrating as I know it's out there somewhere! I'm sure I haven't 
imagined it! Or is that just the creeping paranoia.

Many thanks
