Serena learnt a new word on day three of the Australian Open
"We say booty. I'm not quite sure about 'posterior'. I'll try to keep that in the back of my mind. 'What are you doing?' 'I'm shaking my posterior'."
Serena Williams. She was asked what she thought about a TV commentator admiring slow-motion pictures of sister Venus's "posterior"
"Venus definitely has a great posterior. I'm sure it looked nice."
Serena plays down the rumpus
"We'd need a really long time because all I'll need is a tennis ball and I'm just going to stand here and bounce the ball for a
really long time before I serve. We're going to be here all day long."
Maria Sharapova on being asked for her impression of Novak Djokovic - who has taken to impersonating the Russian
"I avoid stepping on the lines of the court because I believe it brings me luck."
Not sure about that, but at least world number four Ana Ivanovic doesn't think she will get eaten by crocodiles
"Rituals are an important part of my life during tournaments - I am probably one of the most superstitious players on tour."
Ivanovic also bounces the ball exactly four times before she serves and eats at the same restaurant every night
"I always have a song playing in my head. It can be annoying because I can't get it out of my head. In the first round it was 'Wake Up Call' by Maroon 5."
Ivanovic again. It is a wonder she manages to remember to play tennis really
"It was a lot of fun. We will win together next time."
Ivo Karlovic (6ft 10ins) after he and John Isner (6ft 9ins) after becoming the tallest doubles partnership in tennis. They lost.
"Why frustrating? I have 5,700 points so there is nothing frustrating. I'm very happy to be number two, and I would love to be number two for the next hundred years."
Rafael Nadal contemplates a century in tennis when he is asked what it is like to play second fiddle to Roger Federer
"Yeah, absolutely. I thought I'd, you know, push into the 40s."
Alicia Molik plans a long career
"Maybe a year later, now that it seems so far away from me, I can say I missed the tournament but in January a year ago I really didn't miss my tennis because there were more important issues in my life."
But 12 months is a long time for top seed Justine Henin, who did not even watch the 2007 Australian Open after pulling out because of her marriage breakdown
