"When I want to go into town, or I want to buy something, I'll take the Segway, and I'm into town in 10 minutes," he told Forbes. "And I feel happy — I got to skip the whole car thing. The Segway has brought a lot to my life."
Actress Angelina Jolie collects daggers.
In 2008, Jolie told W Magazine that her mom introduced her to daggers when she was a kid, and that she hopes to pass this hobby on to her son, Maddox.

She told the magazine: "We also talk about samurais and about the idea of defending someone as good. We talk about everything."
Google cofounder Sergey Brin enjoys high-flying trapeze.
But perhaps his most unusual hobby is high-flying trapeze, which he began doing at a local circus training center in San Franciso that hosted Google team bonding events in the early days of the company, Business Insider previously reported.
In 2009, Brin took an advanced trapeze class at the Circus Warehouse in New York and a fellow participant told Business Insider that he was impressed with the Google cofounder's skills. "People fly out from all over the world to take this class and learn from some of the masters. I'd say [Brin] was in the top 20% of the class," he said. "He was definitely giving his all."
Billionaire Warren Buffett regularly plays the ukulele and online bridge to keep his mind sharp.
The billionaire Berkshire Hathaway CEO told CNN Money that he also plays online bridge most Mondays with three other partners, sometimes including Bill Gates.
In a report titled "Why Warren Buffett Plays Bridge," economist John P. Hussman reasoned that Buffett's love of the game could be because it places emphasis on "playing a hand right rather than on playing it successfully."
The actor and filmmaker has been collecting vintage typewriters since 1978, according to an Op-Ed he wrote for the New York Times in 2013 about why he does it (spoiler: It's mainly for the typing sound) and his favorite models.
"There is no reason to own hundreds of old typewriters other than the sin of misguided avarice (guilty!)," Hanks wrote.
In 2014 Hanks released an app called the Hanx Writer that gives you the blissful experience of a manual typewriter fonts on an iPad or iPhone, NRP.org reported.
After hearing about his obsession with typewriters, one podcaster decided to send him an interview invitation on a 1934 Smith Corona typewriter, according to a Reddit post. Hanks accepted the invitation with a cheeky, typewritten reply.
Billionaire Richard Branson's favorite sport is kitesurfing.
With an estimated net worth of over $5 billion, Branson has the time — and the money — to take up exotic hobbies like kitesurfing.
The Virgin Group founder told SurferToday.com that he learned the sport on Necker Island — which he owns — in 2002. "It was lethally dangerous," Branson told the surfing publication. "When you fell you'd be dragged underwater 100 feet, and you prayed you didn't hit a reef."
He said he likes to "get half an hour away from Blackberries and iPhones" to go kitesurfing, which allows him to return to work feeling "completely refreshed" and "ready to go."
"I got one for Christmas when I was 10 and taught myself how to use it," she said. "Now I can do all kinds of tricks, like cycling backward and jumping off curbs."

"At a deeper level, running is about pushing the limits, of realizing one's possibilities," he told Bloomberg.

Sarandon, who is part-owner of SPiN, a ping pong social club chain with locations in New York, Toronto, Los Angeles, Chicago, and San Francisco, told the AP: "I love the game because it cuts across gender and age and body type, and you can play it until you die, unlike other sports that you have to abandon at a certain point."
In a 2015 interview with Bloomberg's Emily Chang, Costolo says he spends a lot of time "watching" the bees.

He says he's even taken lessons. "In America there's a program called 'Fly Fishing the World' and I've done about five of them. The last one I did was in New Zealand for about ten days and I brought my best friend. We had two cameras up our noses the entire time, but they're great fun."

Actor Nick Offerman enjoys woodworking.
Offerman may not have been acting when he played Ron Swanson on "Parks and Recreation."
Like Swanson, Offerman is obsessed with woodworking, the Huffington Post reports.
"In my day job, performing for folks is a gas, and I am very tickled to make a nice living as a professional jacka--," Swanson said, "but it is the production of sawdust and shavings that brings me the most profound satisfaction."
Offerman started his own wood shop in East Los Angeles with 10 employees who make hand-crafted tables, chairs, beds, and boats, according to Offermanwoodshop.com.
