When we first meet this polymath, he is performing surgery to remove a pineal tumor from an "Eskimo boy". This is only the start of his day which will end with him playing lead guitar and lead vocals for his band, the Hong Kong Cavaliers, and racing a car across the salt flats to breach the dimensional barrier. Identify this guy who had some problems with a bunch of guys named John, and once cautioned: Don't be mean ... (because) no matter where you go, there you are.
