If you like "Mots...", then try the German version: "Morder Guss Reims: the Gustave Leberwurst Manuscript" by John Hulme C.N. Potter, pub. 1981. For what it's worth, my library has this under the subject heading "macaronic literature". Also, years ago, the Pick'n' & Sing'n' Gather'n' (a fine folk music club) put "Ladle Rat..." and some song lyrics (Lath Thing Thumb Thongs) in their address listing. If I can find my old copy, I'll see if I can put them up. Somebody said that they were part of a psychology test dealing with language perception, I believe.
