I think I have a valid argument for this theory besides people mistaking this with Shaquille O'Neal's 'Kazaam'. In an episode of Nickelodeon's 'All That', Sinbad once played the father of Ishboo (played by Kenan Thompson) 'Sinboo'. And I recall his clothing being very similar to that of a Genie. Can enough people be mistakenly conflating their childhood memories of Sinboo and Kazaam and creating 'Shazaam'..?
