The Clerihew, like most light verse forms, is an excuse for an intellectual type to be clever. Its thrust is biographical – it begins with the name of a famous person and proceeds, in two rhyming couplets of unequal lengths, to say something comical or satirical about him or her. Here is an example of my own composition:
Strolled through the woods and found himself lost.
Said he: “Unless I am mistaken,
“I’ve traveled down the Road Not Taken.”
(For those of you who don’t know, The Road Not Taken is the title of one of Frost’s most famous poems.)
