1. Kirk Cameron -- Most biographies about Kirk state that he was born on October 12, 1970. Guess what that is--WRONG! The truth is, Kirk was born on October 12, 1969 in Panorama City, California, the eldest of 2 celebrity children (including a younger sister, Candace, of "Full House") born to Rob and Barbara Cameron.

2. Jay North -- Jay's IMDB biography states him as the son of singer/actor Hal Hopper, a former member of the Pied Pipers. Guess what that is--WRONG! As Jay himself explained on the "Jay North E! True Hollywood Story," Jay is Hal's nephew.

Another myth, some years ago, was that Jerry Mathers was killed in Vietnam!
NOT TRUE!!

I remember hearing that. Another myth that was around at the same time was that David Cassidy played Little Ricky on "I LOVE LUCY".
