And one might adduce here the poem called 'A Gallop Of False Analogies' which appeared many years ago in Punch by IIRC one St Leger [which here is often pronounced Sellenger ~ as in the well-known old tune Sellenger's Round to which Shirley Collins sings The Fair Maid of Islington], which is based on Sir Izaac Walton's naming of a fish as 'the Chavender, or Chub', which begins

There is a fine stuffed chavender
A chavender or chub
Which decks the rural pavender
The pavender or pub
In which I eat my gravender
My gravender or grub ...

and there is a bit later on about

From sheets as fresh as lavender
As lavender or lub
I leap into my tavender
My tavender or tub

Ah, Sancta Simplicitas
