Part three continues Bill’s disintegration after Everything Will Be OK and I Am So Proud of You. Eventually Bill loses almost all of his memory, then drives away and dies alone in a field – but no, the narrator decides Bill can’t die, not ever, and will regain his senses then wander the earth and the universe for eternity. Personally I wasn’t all that attached to Bill, even after watching the first two segments together with this one as an hour-long feature.

I kinda half-watched this with eyes averted – don’t like dental-horror.
