Billionaire investor Warren Buffett, 86, is quite the character.
In the 2017 Berkshire Hathaway annual meeting, he and longtime business partner Charlie Munger, 93, entertained a crowd of 40,000 with hours of wit and wisdom, including Buffett's opener: "That's Charlie. I'm Warren. You can tell us apart because he can hear and I can see."
Besides being funny, the second-richest man in the world is also frugal. Here are 11 of our favorite Warren Buffett quirks.
He never spends more than $3.17 on breakfast
On his five-minute drive to the office, which he's been doing for the past 54 years, Buffett stops by McDonald's.
Depending on how prosperous he's feeling, he orders one of three items: two sausage patties for $2.61, a sausage, egg and cheese for $2.95 or a bacon, egg and cheese for $3.17.
On mornings when McDonald's isn't an option, such as when he's visiting his good friend Bill Gates, he prefers Oreos for breakfast.

He drinks at least five Cokes a day
"I'm one quarter Coca-Cola," Buffett tells Fortune. "If I eat 2700 calories a day, a quarter of that is Coca-Cola. I drink at least five 12-ounce servings."
His explanation for his sugar-centric diet: "I checked the actuarial tables, and the lowest death rate is among six-year-olds. So I decided to eat like a six-year-old. It's the safest course I can take."
He lives in the same home he bought in 1958
It's a five-bedroom in central Omaha that he bought for $31,500, or about $260,000 in today's dollars.
If you want to be Buffett's neighbor, the house across the street will cost you about $2.15 million.
He has "instructive art" hanging on his office walls
Buffett has copies of old New York Times front pages depicting economic crises, like the Panic of 1907 and the Great Depression.
"I wanted to put on the walls days of extreme panic in Wall Street just as a reminder that anything can happen in this world," he says in HBO's documentary, "Becoming Warren Buffett." "It's instructive art, you can call it."

He's been based in the same office building for more than 50 years
"It's a different sort of place," Buffett says of the small Berkshire Hathaway headquarters in Omaha where he's been investing for more than 50 years.
As HBO's documentary reveals, he likes continuity. He says, "We have 25 people in the office and if you go back, it's the exact same 25. The exact same ones. We don't have any committees at Berkshire. We don't have a public relations department. We don't have investor relations. We don't have a general counsel. We just don't go for anything that people do just as a matter of form."
He doesn't keep a computer on his desk
His work area also lacks a phone. In fact, Buffett has somehow managed to send only one email his entire life. That was to Jeff Raikes of Microsoft.
He reads about six hours a day
"I read and think," Buffett tells Time. "So I do more reading and thinking, and make less impulse decisions than most people in business. I do it because I like this kind of life."
When he's not reading or thinking, he's playing bridge
He spends about 12 hours a week playing bridge, often with Gates.
He once had a vanity license plate that read "THRIFTY"
It was on the back of his Lincoln Town Car.
Despite his billions, he's a careful investor
The Oracle of Omaha has two rules of investing, he says in "Becoming Warren Buffett": "Rule number one: Never lose money. Rule number two: Never forget rule number one."
And he still uses coupons
The self-made billionaire still values a good deal. Buffett once bought Gates, the richest man in the world, lunch at McDonald's with coupons.
