Megan Fox and Mike Tyson are showing that they have a sense of humor in a new commercial to promote Brazilian-based language school CCAA. Random!

The ad, filmed in Oxnard, California, shows two guys who end up on a remote island after a plane crash ... only to encounter the gorgeous Ms. Fox and the words, "Welcome to Megan Fox Island." Then later on, the non-English speaking guys encounter Mr. Tyson ... and the words "Welcome to Mike Tyson Island." The concept is pretty eye-catching!

We'd prefer being stranded ... surrounded by thousands of Megans. Just saying.
