I read the thread title but couldn't see what Jacob's Ladder had to do with

I put my finger in the woodpeckers hole
And the woodpecker said "God bless my soul
Take it out.Take it out
Remove it"

I removed my finger from the woodpeckers hole
And the woodpecker said "God bless my soul
Put it back. Put it back
Replace it"

.....Turn it round
Revolve it

Turn it back
Reverse it

I suspect there may be more, but I can't remember
The tune starts a bit like "I lift up me finger and I say tweet tweet"
