This Old Man
I / / / | IV / V /
I / / / | / / V I
This old man, he played one
he played knick knack on my thumb
with a knick knack paddy whack give a dog a bone
this old man came rolling home

This old man, he played two
he played knick knack on my shoe...

three ... on my knee
four ... on my door
five ... on my beehive  or sakes alive  or that's no jive
six ... on my stick or with those chicks
seven ... up in heaven
eight ... on my gate or far too late
nine ... on my vine or for some wine
ten ... once again

This is a children's song that is good for counting, but I've also played it at bars with good results.  It's a song everyone knows and drunks love to sing along and you can sing really risque lyrics if you like.
