Funny errors

I was born in an  ugly old town

With mill chimneys and  houses  with frowns.

Yet from time im-marmoreal  [should be immemorial]

I loved the arboreal

And I have garbled my marbles  unsound.

Marmalade’s an  orangey jam.

Sevilles are the best for  old men

For the flavour is bitter

Thus makes their tongues gnatter,

Which forces their mouths to uncram.
