Actress Courteney Cox says she is so absent-minded that she can hardly recall many episodes of ‘Friends’, the show that made her a household name.”My memory is the worst of anyone I know. Every time I see an old episode of `Friends`, I`m surprised by what happens because I just don’t remember them,” thesun.co.uk quoted her as saying. She played as Monica Geller on the show.She doesn`t remember the star guests on the show either.”People come up to me and say, `I loved the episode so-and-so was in`. And I`m thinking, `Really? That person did `Friends`,” said the 47-year-old.
