Neil Gaiman's Journal

In Matsigenka (also spelled Machiguenga), IRAPUSATINKAATSEMPOKITASANOIGAVETAPAAKEMPAROROKARITYO is the longest word. It means: "They will probably really go head over heels into the water when they arrive but not stay that way".

In German, the longest word is DONAUDAMPFSCHIFFAHRTSELEKRIT- ZITAETENHAUPTBETRIEBSWERKBAUUNTERBEAMTEN- GESELLSCHAFT (80 letters), "the club for subordinate officials of the head office management of the Danube steamboat electrical services (name of a pre-war club in Vienna)," according to 1996 Guinness.

So you know. Yes, I'm sure there are easier ways to play with margin size than by posting very long words. but at least it's educational.
