There was an HIV/AIDS awareness episode of 'A Different World' where they had an assignment to write speeches for their own funeral, with Whoopi Goldberg and Tisha Campbell guest starring
That scene where Tisha's character, Josie revealed to the class through her assignment speech that she was HIV positive was one of the most powerful and informative moments i'm glad was portrayed on a sitcom
BTW Tisha Campbell's performance was just 10/10, genuine chills
