I saw a whale's tail. Not the top of a g-string poking out the back of a slapper's low-riding jeans - an actual whale tail in Sydney harbour. First real whale tail! Didn't see the rest of the whale, it was refusing to show us everything, the big flirt. The coastguard blocked it off so stupid people couldn't sail their boaties over it, as stupid boatie people like to do - they are also very fond of sailing directly in the ferry's path.
So, whales are big. Quite big. Bigger than Tim, even.
