"the resident of knowledge is a 'wurstendbinder' " - Dieter Roth
Wurstendbinder is a made-up german word describing a person who's tying the ends of sausages; besides "end-binden" sounds similar to "entbinden", meaning to absolve, to give birth. So why should a butcher be the keeper of wisdom and ken? The better question may be 'why not?'.
