I seem to recall something about her working 9 to 5 and having an arch-nemesis called Jolene.

EDIT: Wait! Wait! I remembered! There was a sheep called Dolly who was a workaholic who had herself cloned to spend more time with her partner!

EDIT 2: Ok, I just did a web search. I was way off.

Of course we remember Dolly! She was stuffed and is on display in the National Museum of Scotland.
