Zav to Cav to Fish Eggs

Zaviar’s friends (Zaviar with a ‘Z’)
Called him ‘Z’,
Or Zav (small ‘a’, like in lab).
Liking neither, he changed his name
To Caviar,
Liking the sound of Cav for short.
It was, he knew, a minor pretention,
Like Diamond Jim or Goldy or Champ,
But one, he knew, his friends would get used to…
After all, they were his friends.
So he filed the papers, paid the fee,
And legally changed his name,
Then introduced himself as Cav.
But his friends, being perverse,
Called him Fish Eggs, instead.
So he changed his friends.
