If you're prone to bursting out into tears spontaneously, you may not want to use Google today. The search engine is honouring Fred Rogers [1] with a delightful Google Doodle that's sure to leave you weeping into your cardigan sleeves, just like his documentary did [2]. The adorable stop-motion video features an animated version of the children's show host making his way through the neighbourhood while meeting various kids and singing "Won't You Be My Neighbour?" along the way. It's nearly two minutes of pure, sentimental joy.

Exactly 51 years ago — on Sept. 21, 1967, to be precise — the very first episode of Mister Rogers' Neighbourhood was filmed in Pittsburgh. Relive Fred's nurturing, warm demeanour [3] by watching the entire Google Doodle video below, and then keep reading to see just how emotional it's making people feel. We suggest having a full box of tissues nearby before you press "play."
