Conjecture: pastries shaped like simple mathematical objects are obviously better than pastries that are not. Obviously, pretty torus-shaped bagels are better than crummy off-spherical buns. The Möbius-band cut bagel is the Endlösung of the buttered-side-down problem, and who wouldn’t like a volume- and hence calories-free 2.72683 dimensional Cantor cake (yeah, yeah, Menger/Menger-Sierpinski cake, but awesome alliterations take precedence over crappy crorrectness).
