I've been looking for a song I heard my grandparents sing. Here is what I recall of it.
Hitler had a little ol' yaller dog.
A mangy ol' cur from Tokyo.
On December the 7th, when everything was still
He tried to sic that dog on Uncle Sam.

Well that little ol' yaller dog had a million yaller pups,
They jumped on Uncle Sam and tried to eat him up.
But you know our Uncle Sam, he's a mighty, mighty man.
He chased that litter back to Japan.

There was an ol' hog over in Rome.
He'd have been better off if he'd have stayed at home.
But he kept on a rootin' in the other feller's land,
Til he rooted right into Hitler's hand.
