I always did the song and where you hear "something" I used "mite".Like so---There's a log-------There's a knot-----There's a frog----There's a wart-----There's a hair----There's a flea-----There's a chigger---There's a mite----There's a germ---There's no hole---No more hole---I done filled up the hole in the bottom of the sea.
May not be quite correct, but that's my version. ---redbirdrobb
