Since when can't Buddhist have a sense of humor? There is nothing in the philosophy that forbids laughing and enjoying satire. As a former Baptist I find the the souse of the song extremely funny.
Hell if there is a heaven and by some miracle I make it in I'm hoping God will say "John you funny assed son of a bitch get over here I need a good laugh today."
By the way Do you think there be hummers in heaven?
