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! / 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'll change if you'll arrange to knock on wood! // Who's got nothin'? We got nothin'! / How much nothin'? Too much nothin'! / Say, nothin's not an awful lot, but knock on wood! // Now who's happy? We're 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!
