1) Famous circus 
Circus jossers are not rare, but few remain in circus for any long period of time. It is very seldom that a Josser is seen in the upper hierarchy of a professional circus, their status is usually seen as lesser than that of someone of circus descent. This is due to the aforementioned dedication issue. Jossers are at a disadvantage in modern circus...
Josser is British slang for a simpleton; fool.
fellow, esp. one who is or is made to appear foolish or simpleminded.
