1. Mila Kunis Shares the Advice Robin Williams Gave Her

Mila Kunis worked with Robin Williams in the 2013 film, "The Angriest Man in Brooklyn."

Before he died, she recalled first meeting the actor when she was a teenager starring in "That '70s Show."

2. Secret Mission to Rescue US Hostages ‘Flawless,’ Except for the Rescue

A large contingent of American special operations forces was able to sneak into an ISIS camp near the terror group’s stronghold in Syria in search of American hostages, but quickly withdrew when it became clear that while 100 or so armed terrorists were there, the hostages weren’t, according to a U.S. official with knowledge of the then-secret mission.

The official provided ABC News with new, dramatic details of the raid earlier this summer to grab Americans including journalist James Foley, a mission that Secretary of Defense Chuck Hagel said today was “flawless” except that no one was rescued.

“Knowing their lives were clearly in danger, it’s the responsibility of our leaders, our government to take action when we believe there is a good possibility or chance of making the operation successful. This operation, by the way, was a flawless operation, but the hostages were not there,” Secretary Chuck Hagel told reporters. “We regret that mission did not succeed but I am very proud, very proud of the U.S. forces that participated in it.”

Brown, 18, is seen waiting to join the procession of graduates for Normandy High School in early August, just days before his controversial death on Aug. 9. He is wearing the traditional black cap and gown with a red sash around his neck and the tassel hanging jauntily off the back of his mortarboard.

5. When the Ice Bucket Challenge Goes Awry

A charity stunt that has grown into a social media phenomenon went terribly wrong for four Kentucky firefighters when a fire truck's ladder got too close to a power line after they dumped water on college students who were taking part in an "ice bucket challenge."

Campbellsville Police Chief Tim Hazlette said the power line was never touched Thursday morning, but it carried such a high voltage that it was able to energize the ladder truck, shocking the firefighters.

The two in the bucket were at a hospital burn unit early Friday. One was in critical condition and the other was in fair condition, the hospital said. The other firefighters were treated and released.
