20. Cool and classy under pressure? The teenage Fab Five — There was a lot of pressure on the U.S. gymnastics team this summer to win gold (a feat that hadn't been accomplished since 1996), but as soon as the five ladies started warming up on the mat, the medals were pretty much already clinched. With the skill, composure, and unflinchingly cool personalities to drive the Russian and Chinese teams crazy, this group of women (18 and under, no less) succeeded in complete dominance over the games while still appearing like they were having fun. Plus, our favorite meme of the Olympics, McKayla Maroney Is Not Impressed, really captured the spirit of the Fab Five: Be a boss, never accept second — a 5'2" 16-year-old can still expect (and deserve!) it all.
