In Henderson, Iowa – population, 144 – everyone knows everyone.

In March, residents hold an annual nut fry at the firehouse, advertised as a "testicle festival."

And last November, residents elected Eva Fipps, a 20-year-old who is America's youngest serving mayor. Fipps also says she's the youngest female mayor in U.S. history.

"I didn't think I'd be making American history, I thought I'd just be running my little town, but I am so proud of myself for not getting bogged down, not getting overwhelmed with it," Fipps told USA TODAY.

The online college student won her election by 24 percentage points, defeating her 45-year-old opponent, a truck driver named Scott Schondelmeyer, with 31 votes to his 19.
