The eternal struggle between theoretical and practical mathematics, beautifully illustrated. When dividing a cake into thirds, math says each piece should be 0.333... (repeating), but multiply that by 3 and you get 0.999... not quite 1. Where's the missing 0.001? On the knife, of course! This is why mathematicians make terrible bakers—they forget that real-world division comes with a "cutting tax." Next time your calculus professor waxes poetic about limits approaching infinity, remind them they still can't cut a cake into perfect thirds.
