Meine Freundin ist weg (so wie Schecks aus Amerika).
Geilheit macht mich zum Teilzeit-Polemiker.
Freiheit bringt mich jetzt nicht weiter Mann,
ich frage mich: Was fang ich bloß mit so viel Freizeit an?
Ich hab Chips gekauft und fern gesehen,
VIPs beim Boxen und Kochen im Dschungel — und in den Wehen.
Ich weiß nur: Live ist als Scheiß einzustufen!
Mir wars egal — ich hab 300 mal da angerufen.
