My buddy used to get backstage quite a bit and got to know quite a few peeps. He was told what they are really saying is Won't you please sir drive me to Firenze? It is centered around an acid trip when they were in Italy and tried to get a cab. The Italian driver couldn't understand them very well (and vice versa since they were tripping too). They started laughing uncontrollably and the driver thought they were laughing because he was funny so he said, "What? You enjoy myself?"
