Mario and Luigi have been dealing with the paranormal for years, but there was one time that everyone's favorite plumber pair met their match and needed a professional consultant. When a pesky poltergeist moves into the duo's plumbing shop, who are they gonna call? Ghostbusters Slime Busters! Consider this artifact from 1989 in which Ernie Hudson comes to the rescue in the live action "Slime Busters" bumper segments of DIC's Legend of Zelda episode "The Ringer" on The Super Mario Bros. Super Show to bust a ghost in an unsaid cross-promotion for Ghostbusters II. He's not actually there as his Ghostbusters character Winston Zeddemore, but even as kids we all knew what was really going on here.
