He laughs upon his duty, he laughs upon his beat
He laughs at everybody when he's walking in the street
He never can stop laughing, he said he'd never tried.
And once he did arrest a man and laughed until he died.
I used to put money in slot machines at the seaside and watch a comical caricature sing this song - and I think this rather proves my point about authority figures. Buona fortuna, il signor policeman!
