"Partial Terms Of Endearment" - Family Guy
Family Guy has been airing for years, so it's not surprising that at least one episode has gotten completely canceled. In the eighth season, an episode titled "Partial Terms of Endearment" followed Lois as she decided to become a surrogate for a friend's baby. When the friends pass away in a car crash, she and Pete have to decide whether or not they will keep the baby. Fox didn't like this episode and canceled it from airing. It can still be found on the Season 8 DVD.
"Windy City" - Mike & Molly
Mike & Molly is a silly sitcom that never really dabbled in anything controversial. This situation wasn't too bad, but they did ban an episode due to weather issues. The episode "Windy City" was about tornadoes and bad weather. At the time, tons of tornadoes were destroying the states of Kansas, Oklahoma, Iowa, and Kansas. In order to not draw any negative attention or make light of a bad situation, they pulled the episode. It was rescheduled to air at a later date.
