Bleeding Gums Murphy appears to Lisa in a cloud near the end of the episode with Darth Vader, Mufasa, and James Earl Jones saying "This is CNN". Despite the fact that all three characters were voiced by Jones, the characters in this scene were impersonated by cast member Harry Shearer; Jones himself guest-starred in two episodes before. Additionally, Mufasa accidentally said "Kimba". He corrects himself by saying "Simba". This is a reference to controversy regarding "The Lion King"'s similarity to the anime show "Kimba the White Lion". Lisa and Bleeding Gums play Carole King's song "Jazzman" in this scene and in the hospital earlier in the episode. Bleeding Gums has to leave at the end of the scene because he has a date with the jazz singer Billie Holiday. for the TV Show "ER".
