Though Wikipedia won't tell you this, "Lavender's Blue," the old English folk song, was the original "[You Say Tomato, I Say To-mah-to,] Let's Call the Whole Thing Off."  "Lavender's blue, dilly dilly, lavender's green."  Only in the folk song, they don't call the whole thing off just because they can't agree about the color of lavender.  Interestingly, the lyrics in the 1670s version began with the colors the other way around: "Lavender's green, diddle, diddle, lavender's blue," so the first rhyme used to be about "you" and not a once or future "queen."

A sort of opposite of a mop wig -- a crate of squeeze sponge mops worn everywhere but on the head.  [You may recall that our very own mop wig has been ranked in the top 5 of mop wig looks through history, but we're too modest to quote that; no one dons a mop wig to put on airs].  From Lees-McRae's 1969 yearbook.  

We always hear of musicians selling their souls, but it's also conductors, recording engineers, even album cover artists.  From Witchcraft and Sorcery, 1973.
