For those who may be unfamiliar with the rhyme that the OP is talking about, here it is...

"Taffy was a Welshman, Taffy was a thief,
Taffy came to my house and stole a piece of beef,
I went to Taffy's house, Taffy wasn't in,
I jumped upon his Sunday hat, and poked it with a pin.

Taffy was a Welshman, Taffy was a sham,
Taffy came to my house and stole a leg of lamb,
I went to Taffy's house, Taffy was away,
I stuffed his socks with sawdust and filled his shoes with clay.

Taffy was a Welshman, Taffy was a cheat,
Taffy came to my house and stole a piece of meat,
I went to Taffy's house, Taffy wasn't there,
I hung his coat and trousers to roast before a fire."
