The adder is a British fish -
I'm sorry, I mean snake!
The error's one I've made and wish
I hadn't for its sake:
It drowned quite quickly for a fish,
Though slowly for a snake.
The seahorse doesn’t do divorce:
It picks a spouse for life.
The wife’s the husband and, perforce,
The husband is the wife.
A husband, feeling rightly proud
(As husbands are, of course) ,
Will say of her who’s well endowed:
‘My wife’s hung like a horse.’
