The world's tallest and shortest living men met for the first time in London on Thursday as part of an event to mark the 60th anniversary of Guinness World Records. 

One stands as tall as a red British phone booth. The other is the height of six stacked cans of baked beans.

On Thursday, for the first time, the man with the tallest recorded height in the world and the shortest man in the world met at an event in London, where they posed for photos and stretched for an awkward handshake.

The occasion was the 10th annual Guinness World Records Day, which celebrates record-setting achievements around the globe. The Guinness folks flew the two men, Sultan Kosen of Turkey and Chandra Bahadur Dangi of Nepal, to London for the unique photo op.

Kosen, 31, is a part-time farmer who measures 8 feet, 3 inches tall who became the world's tallest living man in 2009, overtaking China's Xi Shun, who stood a mere 7 feet 9 inches.

Dangi, 74, is just 21½ inches tall and is the shortest adult human ever verified by Guinness World Records.
