You're a sap, Mister Jap
To make a Yankee cranky
You're a sap, Mister Jap
Uncle Sam is going to spanky
Wait and see before we're done
The ABC & D will sink your Rising Sun
You're a sap, Mister Jap
You don't know Uncle Sammy
When he fights for his rights
You'll take it on the lammy
For he'll wipe the Axis right off a map
You're a sap sap sap, Mister Jap

You're a sap, Mister Jap
To make a Yankee cranky
You're a sap, Mister Jap
Sammy's going to spanky
Wait and see before we're done
The ABC & D will sink your Rising Sun
You're a sap, Mister Jap
Oh, what a load to carry
Don't you know, don't you know
you're committing hari-kari
For we'll wipe the Axis right off a map
You're a sap sap sap, Mister Jap

You're a sap, Mister Jap
Oh, to make a Yankee cranky
You're a sap, Mister Jap
Uncle Sam's gonna spanky
Wait and see before he is done
The ABC & D will sink your Rising Sun
You're a sap, Mister Jap
Oh, you don't know Uncle Sammy
When he fights for his rights
You'll take it on the lammy
For he'll wipe the Axis right off a map
You're a sap sap sap, Mister Jap

You're a sap, Mister Jap
Oh, what a load to carry
Don't you know, don't you know
You're committing hari-kari
For we'll wipe the Axis right off a map
You're a sap sap sap
