One I know is a zipper: 5....5..6......5...1...3...5.. Then I grabbed her on the foot 5...5...4....5..6..4...2... And the crew began to roar, 5<..7.2.5..5.. 5.....5....6......5...2..3..4... Oh, Oh, up she goes, she's bound for Baltimore...Only the first line changes, use your imagination, and start at the thigh if you want... Michael Cooney sings it, I b'lieve.
every other last line ends on the tonic. (1).
