Big Bird learns about death
The actor who played Mr. Hooper on Sesame Street, Will Lee, died. The Sesame Street people decided to let the character die too, and used it as an opportunity to teach children about death.
This clip demonstrates how to treat death in an honest and helpful way better than any evasive or euphemistic gibberish I've heard from allegedly mature people.
