Brooklyn Decker is a catwalk-strutting supermodel who can induce whiplash with her swimsuit-clad curves, but in high school the siren had more of a passion for politics than fashion.

On the latest episode of "When I Was 17" -- which premieres Saturday at 11 a.m. ET on MTV -- Decker recalls getting into a heated argument with her teacher over a yearbook layout that would have left her beloved student council out of the tome.

"My friend Ashley and I were in this class. I was the senior class president and Ashley was student body president, and the yearbook teacher did not want to give student council a page in the yearbook," she says, explaining, "We funded all these clubs and we support all these clubs through spirit week and so we thought we deserve a page in the yearbook."

However, their teacher, Ms. Smith, explains that since the student council was full of go-getting teens active in several clubs that would've gotten some shine elsewhere in the annual volume, perhaps preserving space for those other organizations would help spread the yearbook love.

"We had one page left in the book," the teacher recalls. "We were trying to decide what group would get that one last page, and I said, 'Listen guys, the same people who are in student council are in lots of other things and so I think we should give the page to this less visible group in the school.' "

But Decker wasn't having it. Her friend Ashley says, "Brooke just like, lost it," a reaction the model doesn't deny.

"We started yelling things at one another and by the end of the class Ashley took a trash can and just chucked it at a wall. And I walked out of the class and I went like this [makes a provocative gesture] and I yelled, 'Suck it!' to my teacher," she says.

Decker jokingly chalks up the outburst to an overload of heart-racing energy drinks. "I don't know what came over me, I was crazy in high school," she says. "I was like, all hopped up on Red Bull or something, I don't know."
