Roseanne Barr
Roseanne Barr was on top of the world after reprising her role from her popular sitcom “Roseanne” in the show’s revival. Unfortunately, she posted a tweet in which she compared the former adviser to President Barack Obama, Valerie Jarrett, to an ape.
She was called out for her racist comment which ultimately led to the show being cancelled by ABC. But the network loved the TV family so much that they created a spin-off called “The Conners.” Unfortunately, Barr’s character was killed off to ensure she would never be able to come back on the show.
