SOURCE: Bernstein, Jüdische Sprichwörter und Redensarten. A shtreimel is a fur-trimmed hat traditionally worn by rabbis and Hasidic Jews on the Sabbath and holidays. And of course the pig is ritually unclean.
עס פאַסט ווי אַ חזיר אַ שטרײַמל.
Es past vi a khazer a shtrayml.
It's as suitable as a shtreimel on a pig.
