While we don’t necessarily dispute Dino’s assertion above, certainly his reasoning is not, shall we say, nuanced.

After all, he doesn’t seem to cite any of the hard science research that has been done to prove his hypothesis.

Ninja’s theorem, however, can very probably be considered proven.  After all, if one has the ability to sharpen a sandwich to the point where it will pierce a metallic body when thrown (!), it is, in all likelihood, a fairly sharp object.

This is not to say, however, that Ninja could not do the same with a plain-old rectangular sandwich; he is, after all, a Ninja.  But I think it’s fairly safe to say that he knows what he’s talking about when it comes to considering the overall sharpness of objects.  One might consider him an expert in the field.

But who would dispute such a claim?  While technically, I suppose that the molecular makeup of a sandwich is the same no matter how you slice it, but I certainly believe that the average sandwich gains approximately 31% in flavor enjoyment when said sandwich is cut into triangles.  Although the research is still inconclusive, it appears that the additional boost to taste distribution comes from the fact that it is much easier for one to enjoy a proper sandwich-to-crust ratio when eating the triangular shape, whereas the rectangle leads to bites that offer too much crust, or in other times, not enough.

And for those who prefer their bread-and-filling meals with the crusts cut off… there is nothing I can do to help you, comrade.
