PEASE PORRIDGE HOT

This nursery rhyme sounds like something either Seuss or Carroll could have written:

Pease porridge hot,

Pease porridge cold,

Pease porridge in the pot,

9 days old.

Some like it hot,

Some like it cold,

Some like it new,

Some like it old...

Compare Seuss's infamous catalogue of fish:

One fish,

two fish,

red fish, 

blue fish.

Black fish,

blue fish,

old fish,

new fish...

In short, fish, or porridge, ad nauseam (pun intended: the Latin expression means literally "to make the reader/listener feel nauseous")!
