The teams write and perform a new jingle for Chicken of the Sea, including the famous lyric "Ask any mermaid you happen to see - what's the best tuna? Chicken of the Sea." The teams are also asked to create a 30-second radio spot that incorporates a portion of the new jingle. While one team sets differences aside in order to fully utilize their talents, the other team succumbs to panic, feeling incapable of rising to the challenge. With a trip to the final four on the line, one team sings their way to victory, and Trump fires another celebrity. Next he calls on the reigning Celebrity Apprentice, Piers Morgan, to interview the remaining contestants and tell him which two should face off in the finale. After Piers puts each celebrity through the wringer, he reports back - but ultimately it is Trump's decision. With the final celebrities pleading their cases in the boardroom, Trump fires more celebrities and names the finalists.
