He's the finniest, funniest shark you ever saw, Jabberjaw,

[ Oh, that's right: it was the 70s. Of course they have a Bermuda Triangle episode, although thinking it over, I'm not sure there's a need for this story to have been in the Bermuda Triangle. ]

Thoughts:
Madame Sargasso seems to be an evil face in a mirror to start.

( This might actually count as an episode with technobabble, in that they give a name to explain all the apparently magical things that Madame Sargasso does. Unfortunately, that name is ``electro-magical'', which goes right back to not explaining a thing. )

Jabberjaw conjures up a miniature Monoc in his closing magic routine.

Trivia: In 1790 James Madison calculated that, were the Federal capital to be placed on the Potomac River, Southern congressmen would have to travel a cumulative 12,782 miles to reach it, while Northern congressmen would travel a mere cumulative 12,422 miles. This was by way of arguing such a site was not really a ``Southern'' capital. Source: The Grand Idea: George Washington's Potomac and The Race To The West, Joel Achenbach.
