Future poet laureate John Betjeman wrote this at age 13 as a “prep” exercise:

Whatever will rhyme with Summer?
There only is “plumber” and “drummer”:
Why! the cleverest bard
Would find it quite hard
To connect with the Summer — a plumber!

My Mind’s getting glummer and glummer
Hooray! there’s a word besides drummer;
Oh, I will think of some
Ere the prep’s end has come
But the rhymes will get rummer and rummer.

Ah! If the bee hums, it’s a hummer;
And the bee showeth signs of the Summer;
Also holiday babels
Make th’porter gum labels,
And whenever he gums, he’s a gummer!

The cuckoo’s a goer and comer
He goes in the hot days of Summer;
But he cucks ev’ry day
Till you plead and you pray
That his voice will get dumber and dumber!
