Prepare to see Sara Sampaio give the sexiest geology lesson of all time!

Kelsey Hendrix | Jan 19, 2016

Science class never looked SO good.

When we took two-time SI Swimsuit model Sara Sampaio down Route 66 to shoot her 2015 spread, we knew the Portuguese native would be in for a real American treat. Known as the "Main Street" of the States, Sara got to know landmarks along the way like Tex, a 47 foot tall cowboy who's been around since 1959, and she even stopped by a BBQ joint (in her bikini!) to get a true taste of the South.

• Get intimate with the ladies of SI Swimsuit on Route 66!

Somewhere along the way, her tongue-tied interviews and bug-filled stops turned into the gorgeous photos we know you've been gawking over all year. But before you go swooning again, we invite you to sit back, relax and have a good laugh with Sara's 2015 SI Swimsuit outtakes! You know you want to.

BONUS: You'll even get an adorable geology lesson as our brunette beauty attempts to describe petrified wood.

BONUS: See some of Sara's best moments from SI Swimsuit 2014 & 2015!
