The Frandles
"Frandle" is a made-up surname that Mr_Grant applies to a character in a caption, when that character does not need to be a recognizable public figure. He believes it 'sounds' funny, especially when paired with a polysyllabic or alliterative first name. "Frandle is much funnier than a regular name like Smith or Johnson," Mr_Grant explains, "therefore using Frandle instead is value-added Funny!"
"I can't believe it," thought Mary Jo Frandle,
Frandle is also a real surname, but Mr_Grant did not know it at the time. He refuses to recognize the name's historical existence, because he says it is outweighed by the fact that the name still sounds funny.
