They said I was crazy, ambiguous, lazy,
disgusting, fantastic, obscene;
So I hied for my sagebrush and cactus and corn mush,
To see if the air was still clean.
Oh, I hight Don Quixote, I live on peyote,
marihuana, morphine and cocaine,
And may I be twice damned for a bank-clerk or store hand
if I visit the city again.
What is the meaning of "may I be twice damned for a bank-clerk or store hand"?
Does he mean: "I may do something to a bank clerk or store hand, and be damned for this"? Or "I may be mistaken for a bank clerk or store hand"?
