Television bosses have gone green on the set of Grey's Anatomy - by banning plastic bottles. Actress Brooke Smith was pleasantly surprised when she joined the cast full-time for the fourth season of the TV hit to discover each person working on the show has their own thermos flask.

Smith, who has made several guest appearances in previous seasons of "Grey's Anatomy," says, "I got a bottle. I got a little thermos. I think one thing that should be mentioned and applauded is that they have banished plastic bottles from the set. Isn't that cool? It's the first time I've seen it.

"The thermos says 'Grey's Anatomy Season 4.' You have to be responsible with that thermos. You have to bring it with you."
