Two English teachers are walking in the woods

I found a primer on writing poetry, on metre and rhyme and form, by Stephen Fry, of all people. In his foreword, Fry sympathises with anyone who has been traumatised by literature lessons in school:

"The way poetry was taught in school reminded W. H. Auden of a Punch cartoon composed, legend has it, by the poet A. E. Housman. Two English teachers are walking in the woods in springtime. The first, on hearing birdsong, is moved to quote William Wordsworth:

Teacher 1: Oh cuckoo, shall I call thee bird
                Or but a wandering voice?

Teacher 2: State the alternative preferred
                With reasons for your choice."

cp would probably approve - Fry quotes Auden again, this time on free verse:

"The poet who writes 'free' verse is like Robinson Crusoe on his desert island: he must do all his cooking, laundry and darning for himself. In a few exceptional cases, this manly independence produces something original and impressive, but more often the result is squalor - dirty sheets on the unmade bed and empty bottles on the unswept floor."
