Unseen German pop band in a particularly surreal episode (14 July 2002) of the Cartoon Network's hilarious Harvey Birdman, Attorney at Law.
Japanese pop group Shoyu Weenie hired former superhero, now lawyer, Birdman to sue The Neptunes after The Neptunes stole "Mochi Mochi" (SW's number-one-in-Japan song), retitled it "Lovely Lovely," and rode it to the top of the fake band pop charts. Sadly, the song was stolen again by a German group, Tschus Tschus, and retitled to the much catchier "Gefahrt Gefahrt und Helbelschliegelmussenkukrlfahrtfahrt - Undfahrt."
The German is mostly gibberish. The German verb fahren means to travel or drive. "Gefahrt" is the past tense and also it looks like "fart" so there's that.
