Names: Mary-Kate and Ashley Olsen
Character: Michelle Elizabeth Tanner
Called: Michelle, Shorty
Mary Kate and Ashley Fuller Olsen were born on June 13, 1986.  They have a little brother and a little sister.  Ashley is older by three minutes.  Although they look interchangeable, they are actually not identical twins.  This is because Mary-Kate is left-handed, while Ashley is a righty.  There are also a few other differences.  Ashley has a freckle above her lip, and she is also slightly taller.  Mary-Kate is more athletic, while Ashley is more trendy.  They started as Michelle when they were just nine months old.  They were very close with Uncle Jesse, both on and off screen.  Not only were Mary-Kate and Ashley the cutest thing on Full House, but they have also appeared in a bunch of bad movies, and also have recorded a few albums.  Now that's a triple threat if I've ever seen one!  The word is out, I hear the Olsen twins are in production of a new tv show.

Michelle is the youngest (and cutest) of the Tanner girls.  She can't talk for the first two seasons, but once she gets started, there's no stopping her.  All it takes is one "You got it, dude," or "You're in big trouble, mister" for her to steal the show.  The best way to get Michelle to do something is by bribing her with a cookie.  She looks up to everyone, so it is exciting for her to have the twins (Nicky and Alex) look up to her.  I think that Michelle has the coolest friends.  I mean, come on, Teddy, Denise, Derrick and little punk-ass Aaron.  Michelle made the show.  And the "other twins" just couldn't hold the show when Michelle got older.
