* BigNameFan: He's a big reader and music fan, and often name-drops his favorite bands in interviews to help promote them, including the gypsy band Taraf de Haidouks (who appeared alongside him in ''The Man Who Cried'').
* GermansLoveDavidHasselhoff: He's known in the UK for being the most prominent American fan of ''TheFastShow'', even appearing in a cameo in their final special. He even inserted catchphrases from the show into ''PiratesOfTheCaribbean'', including "...and they made me their chief." The other lines ended up on the cutting-room floor.
* MemeticSexGod: Suffice to say he's popular with the ladies.
* TearJerker: Just read his comments on the deaths of his friends MarlonBrando and HunterSThompson. The latter called Johnny and left him a phone message, and when he heard of Thompson's suicide and went to listen to it, it had somehow been erased. "That will fuck with me forever," he says.
* TheWoobie: His life kinda sucked before he made it big.
