My version is still somewhat different then any of those. I forget some words or lines though. I found it once a few years ago, but lost it again and can't find it now. but here goes close as I can get...
Nobody loves me, everybody hates me,
guess i'll eat some worms
fat ones, skinny ones,
let the little ones squirm
bite their heads off, suck their guts out
throw the skins away
Nobody loves me, everybody hates me
guess ill eat some worms
oops, forgot my spoon

Seems like there is suppose to be a few more lines before the last one though. just can't remember. ohwell, just thought I'd throw my version on. Hope it helped someone anyway.
