Four winds throw a feast between them, and poor Mister South burns his mouth on a cold potato. The joke is a small, silly reversal that children like working out for themselves. A short one for adding a funny voice to each Mister.
From Mother Goose / Nursery Rhymes (traditional). See the whole collection.
Mister East gave a feast;
Mister North laid the cloth;
Mister West did his best;
Mister South burnt his mouth
Eating cold potato.
