20. Pumpkin Spice Latte
The Pumpkin Spice Latte from the most dominant coffee chain in the world is one of the few limited-run items that can challenge the McDonald's McRib for fan-base fervor. The fans for this sweet seasonal drink are so dedicated, they grew irate over initial reports of a shortage of ingredients. The drink is pretty damn good, nice on a fall day, but still—first world problems, right?
