I remember my grandparents singing a song that went like this,
Hitler had a little old yeller dog,
a mangy old cur from Tokyo.
On December the 7th, when everything was still,
he tried to sick that dog on Uncle Sam.
Now that little old yeller dog had a million yeller 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.
Now there was an old hog over in Rome.
He'd have been better off if he'd stayed at home.
But he kept on a rootin' in the other feller's land
til he rooted right into Hitler's hand.

That's all I remember of it, and was wondering if there was more? or if anyone even knows this one.
