One year after 9/11, Mister Rogers came out of retirement to deliver this message and remind viewers how much he cares about them. In the words of Fred: "It's such a good feeling to know that we're lifelong friends." | Fred Rogers Productions

ON THIS DAY: "Mister Rogers' Neighborhood" made its network debut back in 1968. Produced in Pittsburgh, the beloved children's TV program continued until 2001. https://bit.ly/2N2HHXz | WTAE-TV Pittsburgh

I've been revisiting a lot of great clips from Mister Rogers' Neighborhood after seeing Won't You Be My Neighbor?, and I found this montage of "It's Such a Good Feeling," the song that ended every episode from 1976-2001, to be particularly moving. It includes the first time the song was used and the final moments from the last episode. Credit goes to Baby Lamb Creations on YouTube, who put this beautiful montage together.

"Respecting and loving your neighbor can give everybody a good feeling." It's #WorldKindnessDay. The floor is yours, Mister Rogers. | GBH
