Here's one that has haunted me all my days- ever since I first encountered it in the 1949 edition of The Saturday Book, an annual for grown-ups which made a highly desirable Christmas present. It comes from a set on "Some 18th Century Worthies" and deals with the poet Thomas Gray- author of "The Elegy Written in a Country Churchyard"- a very wonderful poem on one of my favourite subjects which is less well known today than it was in my youth. It's the work not of Edmund Clerihew but of his son Nicolas- the artist- and comes complete with one of his distinctive illustrations.
There was something slightly fey
About Thomas Gray,
As you might have assumed
From his meditations on the entombed.
