No Mutants Allowed

Alternatively, one of the crucial points is to put Penis shapes everywhere.

Depending, but yes, one or the other. Go over the top with it or avoid it completely. Do not confuse the people observing the fantasy world.

Sneak them in everywhere so people see them but are afraid of commenting on it at risk of being labeled a pervert.

I take it back. Put them in sparingly so those who notice are very doubtful and question themselves. If there are too many they'll notice a trend.

Leave ONE continent or map just one big penis-with-balls, then *insist* that "you're seeing only what you want to see"

Ah the Watchmen shuffle, yes.

Ever heard a man with double "R" for his middle names? He simply use Pangaea map with real world continent as reference. I guess you can't go wrong with making fantasy setting with alternate history overlay.

Ehm, if you're refering to Tolkien, whatever map he used - he only published - afaik - a corner of it, and it is only in the past decade that we know what the coastlines of Pangaea would have looked like, beyond the continent being vaguely lump-shaped

I'm going to go out on a limb and assume that this is a bit of an apocryphic 'factoid', since there's no telling if it is or isn't, it'd be like pointing to a star in the sky and saying it's based on another star in the sky, there's no way of telling...
