Radio station WPLJ New York was mocking the ex-Today host’s ratings woes in a send-up set to the tune of Jimmy Buffett’s "Margaritaville." To hear the song, click here (mp3 file – this may open a Quicktime file).
"They hired a honey for sick lots of money/hoping their news would become number one," goes the opening lyric. "They’re not even lurking. The plan isn’t working/Can’t beat Brian Williams or Charlie Gibson."
And here comes the chorus: "Cause poor Katie Couric can’t get out of her own way/And I bet she’s sorry that she left Today." The song was written and performed by Todd Pettengill, co-host of WPLJ’s Morning Show.
