Jane Fonda once saved her grandson from a bear after it broke into her house and urinated on her rug

• Fonda told Jimmy Fallon she once heard a strange noise from her then 3-month-old grandson's room.
• There was a bear in the room, but Fonda scared it off by opening her bathrobe and screaming.
• The bear then peed on her antique rug, turned around, and ran away.

Jane Fonda has had a pretty extraordinary life. Actress, activist, model, environmentalist, two-time Oscar-winner, and now scarer of bears.

Appearing Tuesday on "The Tonight Show Starring Jimmy Fallon," Fonda recalled how she once scared off a bear, saving her grandson, who was three months old at the time, after it broke into her house and peed on her antique rug.

"I was in bed and I heard this weird noise - like the rattling of a door. I got up and went into the living room and I turned around and my golden retriever came running out whelping and yelling," Fonda said, recalling the wild story.

"I'm like, 'what's this?' And I go running in - whoo! There's a bear! Right in the middle of my small bedroom, heading right for my grandson's crib, but I knew what to do," Fonda said.

The actress said that she opened her bathrobe and screamed at the bear. This seemed to do the trick, scaring the bear away.

"The bear urinated on my antique rug and then turned around and sat down. I roared again and it went out to the door and it sat down. There's the hole in the screen door that it came through. I pushed it out and slammed the glass door," Fonda said.

When Fonda told the story, the actress and Fallon were playing a game called "Best, Worst, First," and Fonda had to name the worst uninvited guest she's ever had. Sadly for the bear, there was only one choice for Fonda.

In the "best" portion of the game, the Hollywood icon told Fallon that her best kiss (that also happened to be her first kiss) was with "Mr. Novak" leading actor James Franciscus.

In the "first" section, Fonda, who has been arrested five times while protesting, spoke about her first Zoom rally, which had so many guests in the video chat that it promptly crashed.

Fonda is famous for her activism, and once recorded her BAFTA award acceptance speech while getting arrested for protesting climate change.
