A tiny, nonsensical sketch of a man who lives in a little house and fishes in other people's ditches. Its short, tidy rhyme is easy to remember and quick to repeat.
From Mother Goose / Nursery Rhymes (traditional). See the whole collection.
Little Tommy Tittlemouse
Lived in a little house;
He caught fishes
In other men's ditches.
About this rhyme
A tiny character sketch in four lines: Tommy Tittlemouse in his little house, catching fish in ditches that aren't his to fish in. It's mostly mischief and rhyme, the name chosen for its sound as much as anything.
Short enough to say twice in a row.
