Here's your lyrics - Looks like there's a coupla versions floating around - this one by Louis Armstrong - I'm a big fan of his, but don't think I've heard this one before . . .
I'll be glad when you're dead, you rascal, you!
Oh, you rascal, you!
Boy, I brought you into my home;
You wouldn't leave my wife alone;
I'll be glad when you're dead, you rascal, you.
Now, I'll be glad when you're dead, you rascal, you!
I'll be tickled to death when you leave this earth, you dog!
Hmmm, I took you for my friend,
The way you bit me in the back was a sin;
You ain't no good, you rascal, you!
As I said before, I'll be glad when you're dead, you rascal, you!
Hmm, yea-ee-yea, you rascal, you!
Boy, when you're laying six feet deep,
No more fried chicken will you eat;
Aw, you dog, I know that'll break your heart, ha, ha, ha, ha!
Boy! Boy, what is it that you've got
That makes my wife think you're hot?
Oh, you dog, you ain't no good. Naw!
You bought my wife a bottle of Coca Cola,
So you could play on her victrola;
Ha, you dog! Yes, sir!
