Mr. Rogers' channel thumbnails would look like one of those full-completion video-gaming channels that involve a controller-holder, sometimes along with a confused roommate or neighbor, logging hour #73 of a 20hr RPG because they can't figure out how to get a platinum on the last minigame. There'd be a blurry background of the handpuppets and two headshots of Mr. Rogers smiling and his guest freaking out. I think the titles would be fairly tame, though; I'm imagining, "Another Day in the Neighborhood #112 | An Unexpected Guest, Learning to Tie Shoes"

Now, where it gets fun is imagining that Lamb Chop could have the same setup. "Lamb Chop & Friends #52 | She's Unstoppable, So Much Blood, Can We Unsummon Lamb Chop?"
