Geraldo Rivera

Geraldo Rivera is an American attorney, journalist, author, reporter, and talk show host.

History
When Homer was in a mental hospital their phone had Rivera on speed dial.

During the heyday of The Be Sharps, one song that Homer tried to write had the lyrics, "There was nothing in 's vault, but it wasn't Geraldo's fault".

Non-canon
In Homer's nightmare, Marge and the kids watched The Tonight Show during one of 's sketches, where he reads what is written inside an envelope. Carson as Carnac said, "Geraldo Rivera, Madonna, and a diseased yak." They never got to hear the punchline, however, as first started laughing, and then Marge said that Homer had been mising for two days.

In one of his Christmas origins stories, Grampa said that Rivera had discovered cookies in Al Capone's vault in 1987, after they had been banned since 1929.

Behind the Laughter
Homer's songwriting lyric and the cookie discovery recounted by Grampa both refer to the television special  (hosted by Rivera), where after a huge media buildup the vault was anticlimactically discovered to be empty except for dirt and debris.
