Advantage Ferrell as Will lightens mood

MELBOURNE - American actor and comedian Will Ferrell isn't just at the Australian Open this week for the tennis. He also came to (jokingly) announce his retirement from acting.

"I have kind of done all the movies I want to do. It's a great way to go out," Ferrell told the media at Melbourne Park on Thursday.

It was just one of several lighthearted moments during an unusual news conference with former No 1 Jim Courier that felt more like an impromptu comedy club routine.
