Don Novello played and created the character Father Guido Sarducci. Although the character appeared on Rowan & Martin's Laugh-In beforehand, he's best known for being on Saturday Night Live.
It might be questionable in the U.S but personally, I associate the name Guido with one of my all-time favourite fictional characters, Guido Mista. A charming guy really.

Guido was the alias used by Guy Fawkes while serving the Spanish.
Famous bearer: The birth name of Early Italian Renaissance painter Fra Angelico (c. 1394-1455) was Guido di Pietro. He took the name John (Giovanni) upon entering the Dominicans, and earned the nickname "Angelico" from his contemporaries, thus Fra Angelico, meaning "Angelic friar". He is also called Beato Angelico in Italian, and was officially beatified in 1982, with his feast day on February 18th. He is one of the patron saints of artists.
