I think basically what you have here is an example of bad cropping. The full uncropped "lizard" would be much less "suggestive", but likely not fit into a 32x32 icon. Which of course is just one for reason to use Mac OS X IMO :-P
Of course, if you really wanna get picky about phallic/vulvic symbols, then you could say that the Washington Monument in Wash. D.C. is really just a "symbol" of white-male domination. And then there is the shape of George Washinton's wig on the one dollar bill. Oh, and what about the CBS "eye", i mean come on, thats clearly a vagina turned on its side. Lets not get started on anything paintings by Georgia O'Keefe. And we all know what a cigar really is (wink wink, nudge nudge say no more).
But then again, sometimes a cigar is just a cigar, and a lizard is just bad art direction.
