I-Dubuque, eyaziwa nangokuthi "i-Ugly Betty" ngabasebenzi bayo, iwuhlobo lokusika lwe-dredge.
Ifakwe ithuluzi lokusika elizungezayo elikhulula futhi likhiphe inzika esiteshini sokuzulazula esibe sesimuncwa epayipini elingu-12" ububanzi bese likhishelwa endaweni ejulile yesiteshi elibhekwa njengelifanele ithimba lenhlolovo.
