The First Movie/TV Show That Really Scared Me

I cannot prove this film or TV show actually exists.  I have scoured the Internet since the late 90s for any other mention of this existing.  Every now and again I'll get a "that sounds familiar" or a "I think I remember something like that" but nothing ever comes of it.

It's the first time I ever screamed in fright at something on television (also possibly one of the only times I've ever screamed in fright at the television).  It was a goofy, dumb program with an obviously rubber mask.  I was watching it with one of my best friends, a girl who lived three doors down from my house at the end of a cul de sac.

There are no pictures for this post, because again I can't prove this program ever existed, but I have recently enlisted the help of I Remember This Movie... to help me figure it out.

Because seriously, if they have someone who remembers episodes of Bone Chillers, they should be able to help me with this.
