At the time I watched SNL whenever I remembered, but not regularly enough. However this one commercial spoof has stuck out with me, and I see it referenced all the time. Almost as if it was constantly reused. So how did this one-time event (well, plus reruns and now internet memes) stick in our collective conscience?
Same with Douglass Adams -- I ran across it due to "Adams" being at the beginning of the alphabet, but it also seems that most geeks have consumed it also.
HFB had meme-like qualities even back then, to the point where it was referenced in a completely different skit (Unfrozen Caveman Lawyer).
I think it has to do with the increasingly dire warnings for what is marketed as a children's toy, culminating in the one about not taunting it with deliberately unstated, therefore presumably very grave, consequences for taunting it. The humor is in what is left unsaid, where your imagination takes over.
