My heart has been troubled of late by a certain lack of familiarity and application of several important, erudite expressions in the English language. Therefore, I implore you, make great effort to insert the phrases "the bee's knees" and "the cat's pajamas" into as many of your conversations as possible. The time is long overdue for their return to popularity. For those of you skilled at the use of these idoms and seeking something more daring, perhaps you could try out the lesser known variations: "the flea's eyebrows" and "the sardine's whiskers." Others are certain to look upon you as jaunty and smashing.
