A Serious Poem? Revisited

I tried to write

a serious poem

once;

I did!

Never again!

I felt myself to be a proper Charlie,

a dunce.

I couldn’t get the words to rhyme,

and scan,

and the metre was wrong

(perhaps I wasn’t writing in Metric,

I’m an Imperial man);

and, worst of all,

(which is why I’ve written this all forlorn);

it was

so

serious

that it made me yawn.

I’ll make it plain,

I won’t make that mistake again;

best to keep it funny –

on with the punny!
