Bill Gates and Warren Buffett just proved to the world that their friendship is the definition of #SquadGoals.

Gates on Wednesday tweeted out the pair’s first ever virtual reality video of them romping around the 2016 Berkshire Hathaway BRK.A, +0.36% BRK.B, +0.07% shareholders meeting.

The dynamic duo travel around the show floor mostly via golf cart, visiting vendors including Dairy Queen. Buffett eats a vanilla orange bar, while Gates opts for a Dilly bar. (Buffett is the CEO of Berkshire Hathaway, which owns Dairy Queen.) Then, Buffett breaks out his famous ukulele and they sing “I’ve Been Working on the Railroad” together.

If Gates’ selfie tweet didn’t already make you smile, wait until you see the entire virtual reality video. Watch it on Bill Gates’ site here. If you only came here for the ukulele, skip to the 2:59 minute mark.

Gates wrote in a post accompanying the video that he met Buffett in 1991 at a meeting of a group of friends, which Gates says he initially didn’t want to attend.

“I agreed to stay for no more than two hours before getting back to work at Microsoft,” Gates wrote on his site. “Then I met Warren.”

Gates says he was struck by the questions Buffett asked him about his company.

“We were suddenly lost in conversation and hours and hours slipped by. He didn’t come across as a bigshot investor. He had this modest way of talking about what he does. He was funny, but what impressed me most was how clearly he thought about the world,” he said. “It was a deep friendship from our very first conversation.”

Gates says one of the most surprising things about Buffett is that he eats like a 6-year-old (mostly hamburgers, ice cream and Coke). Buffett once fed Gates’ kids Oreos for breakfast.

Buffett still drives to the airport to pick up Gates whenever he flies into Omaha.

“I’ve learned many things from Warren over the last 25 years, but maybe the most important thing is what friendship is all about,” Gates said. “Everyone should be lucky enough to have a friend who is as thoughtful and kind as Warren. He goes out of his way to make people feel good about themselves and share his joy about life.”
