Coneheads Christmas Special?

Hi,
This might not be quite the right forum since I "know" the cartoon that I am looking for. The problem is I can find no information that it even existed. Nothing on IMDB, Wikipedia or here. In 1983 a special did air on NBC. It was basically a pilot for a series that was never picked up. This special had nothing to do with Christmas.

This is what I remember: I remember seeing a commercial for a Coneheads special which I have in my head as being a Christmas special. I also seem to remember the commercials being on a syndicated channel. I don't recall if I ever watched the show or not. I was too young at the time to know about SNL or who the Coneheads were, so this would have been the first time I ever heard of them. I distinctly remember the commercial using one of their signature lines about "consuming mass quantities". I suppose I could be misremembering things concerning the 1983 special, but I don't think so. 1983 seems too early for me to remember a show like this and it seems odd that I would have known about a show that aired in prime time and was not intended for kids. If I had to guess, I think it would have aired a few years later, like 1986 or so.

So does anyone else remember this special? Or was this some sort of hallucination on my part?

Thanks for the response. I took a quick look at a copy of the book on Amazon. All I could see was a table of contents, but it looks like this is the 1983 pilot episode that I mentioned, and not a Christmas special.

(I think) it was a Halloween special.

Possible. I think I might have to chalk this one up to false memory.
