Ken Kesey On A 20 Euro Bill

Strange things happen in life. About a week ago I got a 20 euro bill with the following words and things on it:

ESTRECHA LA MANO A-TODO EL MUNDO,

EXCEPTO AL GRAN GEORGE, EL MANIÁTI-

CO DEL AGUA, QUE HACE UNA MECA Y

REHÚYE ESA MANO POCE ASÉPTICA, DE MODO QUE

McMURPHY SE LIMITA A SALUDARLE Y,

MIENTRAS SE ALESA, LA DICE A SU,

PROPIA MANO DERECHA:-|MANO, ?CÓMP

CREES QUE ESE TIPO HA PODIDO DESCU-

ERIR TODO EL MAL QUE HAB HECHA? [KEN KESEY]

Don't know which language this or what it means, but I guess one flew over the cuckoo's nest.

By the way, on the 7th line there's a question mark that's actually upside down on the bill.
