I eat pretzels like Darwin would have. It's a constant survival of the fittest competition. I select two pretzels, eat whichever is most flawed, select another, re-test, and just keep going from there. At the end I've got the best pretzel of the whole bag left, which I then eat.
Admittedly it's not an actual test of the pretzels' fitness to survive -- the pretzels with inferior qualities aren't dying off due to failure to feed themselves and attract mates. Really it's just their ability to conform to my invented notion of the master pretzel, but if you go around saying you eat pretzels like Hitler people back away slowly.
