Not many people are aware that the star of the comedy series Saved by the Bell, Tiffani Amber Thiessen, auditioned for the role of Rachel Green and almost got it. The only obstacle to her final approval was her age. At the time the first episode of Friends came out, Tiffani was only 20 years old. Even Jennifer Aniston, at 25, was the youngest of the cast.
