Right on cue.."There stood a cooUpon a hill.It's no there noo'It must've shifted"William Topaz McGonagall (I think).
Not all bad versification can be ascribed to the Great Tragedian. This isn't in my little tome on WTM. It sort of sound plausible but I don't think he is given to a lot of Coos and Noos. I'm sure it was the Topaz that "did" for him.
"Widely attributed to..."Actually normally rendered as "On yonder hill there stood a cooIt's no there nooIt must've shifted"
