"Bored, She Hung Herself" - Hawaii Five-0
An episode of Hawaii Five-0 that aired in 1970 was titled "Bored, She Hung Herself." Obviously, that is a pretty heavy title for an episode. It was about a young woman who dies from an alleged suicide. It turns out, she died trying to master a yoga pose and accidentally suffocated. Sadly, one viewer tried the pose themselves and suffered from the same fate. The episode was cut.
"Elephant Issues" - Tiny Toon Adventures
Tiny Toon Adventures was all about the Looney Toons characters, but small! It was supposed to be a family-friendly show, but they fell short with one episode. The episode "Elephant Issues" had a segment called "One Beer." The segment follows a few of the characters who find an unopened beer. They end up getting drunk and stealing a cop car. The message was supposed to be that drinking is "bad" but it was still pulled due to the lack of clarity on the message.
