Double Happiness is a cigarette brand in China . My wife is Chinese , and I have spent a bit of time over there . I imagine that in the future all the Chinese will be rich and drinking coffee and living lives as jazz musos and artists while the Americans work in factories to build electronic gadgets and phones for them . Here is the song Lyrics . Zhang-san and Wang-Wu are chinese names with numbers in them . There are so many Chinese people that a son will often become Zhang number 5 etc ... San means 3 and Wu is 5 .
in an LA factory
we gotta build some brand new phones
ones for the shanghai master of tone : Zhang-san
Wang-wu's heading down to the double happiness cafe
he'll take his americano grande
and he'll head home to work on his saxophone
