Tori, an orangutan at an Indonesian zoo, has developed a smoking habit. Now it's up to her keepers to break it for her health and safety.

Don't believe us? Here's video of her smoking:

How did Tori pick up the habit in the first place? Because of visitors at the zoo and their smoking habits. Apparently, visitors would smoke while watching Tori and then toss in their butts. Tori picked them up and began imitating them. Over time, visitors began lighting cigarettes and throwing them to Tori to get pictures of her smoking.

It took ten years for the zookeepers to notice this, for some reason, and now poor Tori is being moved away from people. It's not clear how much her smoking has affected her health, but hopefully she'll be OK.
