It's no secret that Megan Fox has serious sex appeal, but is it enough to make Portuguese-speaking teenagers pick up English?

From the looks of this ESL (English as a second language) commercial hitting the TV airwaves in Brazil, that seems to be the goal.

In the ad, a midriff-baring Fox , 25, and several of her hot-bodied clones welcome two stranded teenagers onto "Megan Fox Island" and plead with the boys to speak English to them.

But once the tongue-tied teens fail to come up with the words in English, they get booted and turn up on a fiery "Mike Tyson Island" where the famed heavyweight boxer greets them.

Watch their fate in the clip above, and weigh in below with your thoughts on Megan and Mike's message.
