May 15th is a beautiful day for Mister Rogers' Neighborhood fans. Starting at 3PM on the 15th, Twitch will begin streaming all 886 episodes of the beloved kids' show. The broadcast will last for 17 days on the Mister Rogers channel, ending sometime on June 2nd. Since the show ran from 1968 to 2001 on Public Broadcasting Service (PBS), expect to see lots of episodes you've never seen before, including those that were only ever aired once. Twitch will kick off the event with something other than its first episode, though: it will start by broadcasting Fred Rogers' famous Senate testimony to celebrate its 48th anniversary earlier this month.
