JanuaryLight: raincoat

Why am I posting a picture of a raincoat? Because it reminds me of this couplet from the song Big shot, by the Bonzo Dog Doo-Dah Band, which has always tickled me:

A punk stopped me on the street. He said, “You got a light, Mac?”
I said, “No, but I’ve got a dark brown overcoat.”

I don’t have a dark brown overcoat, but I do have a light mac! On this penultimate day of the January Squares words ending in light challenge I hope you will also delight in the joke. Or maybe you won’t. Forgive me, Becky, for mucking about with your theme.
