Lyrics Knock on Wood - From "Casablanca" - Dooley Wilson

Say, who's got trouble? (We got trouble)
How much trouble? (Too much trouble)
Well, now don't you frown
Just knuckle down and knock on wood

Who's unhappy? (We're unhappy)
How unhappy? (Too unhappy)
Oh, oh, that won't do
When you are blue, just knock on wood

Who's unlucky? (We're unlucky)
How unlucky? (Too unlucky)
But your luck will change
If you arrange to knock on wood

Who's got nothing? (We got nothing)
How much nothing? (Too much nothing)
Say, nothing's not an awful lot
But knock on wood

Ha-ha, now who's happy? (We're all happy)
Just how happy? (Very happy)
That's the way we're gonna stay
So knock on wood

Now who's lucky? (We're all lucky)
Just how lucky? (Very lucky)
Well, smile up then and once again, let's knock on wood
