Here's some information that isn't what Ricky said to Lucy, but it is what "Ricky" sung:

""Babalu" was the signature song of "Ricky Ricardo," the character played by Desi Arnaz in the classic television series I Love Lucy. In its sixth and final season, Ricky becomes part owner of the fictional "Tropicana" nightclub, where he was a regular performer, and renames it "Club Babalu."...

In the religious system of Orisha worship, Babalu Aye (also known as Omolu, Shonponno, Obaluaye, Shakpana, Sakpata) is the spirit of illness and disease. He is an Orisha, the son of Yemaja and Orungan.[citation needed], in certain places he is known to be the son of Nana Omolu, the Fon deity added to the Yoruba pantheon, and associated with Female power and creation. Babalu Aye is also known in Brazil as Obalu Aye. Omolu means the father of this Earth or the king of this Earth, because of his great powers detailed in many Odu Ifa. He is known as the deity associated with insanity,aging ,illness, disease and death, but is also the deity that cures same. He is appeased on the earth and cool water is one of the mainstays of his appeasement.

The origins of this deity trace back to the Fon traditions of Yoruba mythology [Nigeria, West Africa] and appear in Cuban Palo Mayombe (as Pata en Llaga or Cobayende), Haitian Voodoo, Brazilian Umbanda (as Abaluaye), and Candomblé Ketu (as Obaluaiê).

In Cuban Santeria, Babalu Aye has been syncretized with Saint Lazarus"...
