The expression BEE’S KNEES first emerged in the 1920s as part of a trend for inventing random phrases alluding to animals, all implying the pinnacle of excellence. Others from the time included the CAT’S CUFFLINKS, the ELEPHANT’S INSTEP, the HEN’S EYEBROWS and the CLAM’S GARTERS. (via @HaggardHawks)
