During the opening scene of "All the World's a Stage" Kirk Cameron, Chelsea, Nobel, and the rest of the singing waiters sing the show's theme song "As Long As We Got Each Other" instead of B.J. Thomas after they finish singing "On Broadway".
Kirk Cameron's real life father Robert Cameron plays Older Mike in this episode.
The title is a line from William Shakespeare's play 'As You Like It': "All the world 's a stage, and all the men and women merely players. They have their exits and their entrances; And one man in his time plays many parts."
