A riddle rhyme describing 'Old Mother Twitchett', with one eye, a long tail, and a habit of leaving a bit of herself behind at every gap. The answer is a needle and thread, and working it out is half the fun.
From Mother Goose / Nursery Rhymes (traditional). See the whole collection.
Old Mother Twitchett had but one eye,
And a long tail which she let fly;
And every time she went through a gap,
A bit of her tail she left in a trap.
