Oberlander is a very insecure and hyperactive man. On a number of occasions he begs the public, and the whole of San Fierro to hug him and even cries on a song intro. One of two callers is Hans' father who orders him to play some "Wagner", and Oberlander possibly does drugs as his father continues to say "your mother found these pills in your room". Oberlander also inquires if his dealer has shown up yet in another song break.
Hans is voiced by Lloyd Floyd.
Many believe that Oberlander is also the Hans mentioned in a Grand Theft Auto III commercial because of his German accent, but this may not be true.
