'The Late Show Starring Joan Rivers'
Debut: October 9th, 1986
Lifespan: Eight months
Before she was sentenced to a lifetime of policing fashion and plastic surgeries, comedienne Joan Rivers was a favorite of then-Tonight Show host Johnny Carson. Rivers parlayed her many visits to Carson's show into her own late-night gig for Fox in 1986. However, by May 1987, weak ratings and backstage tensions led to Rivers' dismissal. Fox experimented with dozens of guest hosts – including Frank Zappa, who was fired before he ever filmed an episode – but The Late Show was eventually canceled later that year. Rivers did leave us with this gem though: Prince protégé and Last Dragon star Vanity revealing this about the Purple Rain singer: "When I first met him at the American Movie Awards, I thought he was gay."
