Pee-Wee’s Playhouse 1988 Christmas Special Remastered In 1080p

This is the entirety of the 1988 Pee-Wee’s Playhouse Christmas Special lovingly remastered in 1080p high definition. Now I’d be lying if I said I remember it, but I probably did watch it. What can I say, 1988 was a long time ago, and my memory isn’t what it used to be. What used to burn as bright as the sun is now little more than a fart ignited by an idiot at a holiday party, melting the tinsel of his ugly Christmas pants.

Keep going for the whole video, as well as three clips of different highlights.
