Mine will be super greasy this weekend after they have their haircuts. Probably even worse after it rains. Slippery little suckers they are!! One of mine (a Merino) is particulary greasy. he has so much lanolin in his wool that his wool goes stiff as a board if it's been hot, then gets cold again. After he's been shorn, you can see it running off him on hot days. It can get quite gross.

IT'S SHAUN THE SHEEP!!!!!!! (No, I don't have a shaun)
