Where can you watch Dexter's Rude Removal?

Answer 1

According to sources, it's nowhere. But it aired at a comic convention in 1998.

The panel for Dexter was with a special guest being Genndy who delighted us with some oncoming specials and such. He then hinted that he also wanted to show us something 'truly special' at the end.

Nearing the end, a girl from CN stood up and announced that everyone under 18 needed to stand up and would be given something special but had to leave. The kids filed out as the adults kind of looked at each other with a big ? over our heads. Genndy kept grinning.

After all the kids were shooed, Genndy looked at the remaining 20-30 of us and said "We made something special as an inhouse project to show only at CN parties and the like...I loved it soo much you guys are gonna get a treat...Dexter's Rude Removal"

The girl then stood in front of us and warned us with bodily harm if she caught any of us taping anything or even remembering hard. She was pretty much imagining it getting out there and torpedoeing CN with lawsuits. "I want you people to know this will NEVER be made public...so count yourself extremely lucky". Finally Genndy shooed her away.

UPDATE: Recently on October 2012, Genndy Tartakovsky was asked about the episode and he replied "Next time I do a public appearance I'll bring it with me!". A week later, Adult Swim aired a bumper about the episode and said "We'll try to get the episode to air. [stay tuned]". Later on, that same month, there was a reply for an update on the status of this episode, with the Adult Swim boss saying that: "We'll think about it". A third and final update later on gave an update that Adult Swim had the video and would put it up online with a hashtag to "#telljeff" on Twitter.
