Megan Fox is still one of the prettiest person on earth. This will encourage young students to watch the show and learn about lost historical places like the pyramids in Artic or the greater wall of Mongolia. Imagine if it was hosted by Betty White or Morgan Freeman. No one would watch that. That would be disturbing on so many levels.
Meanwhile MGK is just like Eminem in his younger days. Minus the midlife crisis ofcourse.
