Doc & Mharti. Probably still on the Channel 101 web site. It’s literally just Marty McFly licking Doc Brown’s balls and jerking him off in close-up. I have no idea how it became a tv show.
I thought this was an amusing thing to run for April Fool’s. It was better catching it halfway through at the start, having no idea what is was or how long it was.
Until Season Four is ready, they could just air guest shorts from alternate universes as far as I’m concerned.
