Only one of these candies can be the greatest of them all.
Well, it's not about movies, exactly, but it is from Roger Ebert. The letters section on Ebert's blog includes a gem from a gentleman named R. Crutch, who explains that he is investigating candy with an evolutionary perspective:
Whenever I get a package of plain M&Ms, I make it my duty to continue the strength and robustness of the candy as a species. To this end, I hold M&M duels.
Taking two candies between my thumb and forefinger, I apply pressure, squeezing them together until one of them breaks and splinters. That is the "loser," and I eat the inferior one immediately. The winner gets to go another round.
I have found that, in general, the brown and red M&Ms are tougher, and the newer blue ones are genetically inferior... .
Believe me, there's more where that came from. Read the whole thing.
