My granny taught it to me when I was little. We use to sing it every time we went camping or took a long car ride. Here is what I remember of it.

"Nobody like me, everybody hates me,
sitting in the garden eating worms all day.
Big fat juicy ones, slip slop sloppy ones,
sitting in the garden eating worms all day.
First you pull the heads off, then you suck the Goo out,
then you throw the skins away.
Nobody likes me, everybody hayes me,
sitting in the garden eating worms all day"
