Guinness World Records Day brought together two unlikely friends Thursday: the tallest and shortest men in the world. Sultan Kosen, who is 8-foot-3 and from Turkey, met Chandra Bahadue Dangi, who is 21.5 inches and from Nepal. The distance from the top of Dangi's head to Kosen's is 6 feet and 6 inches -- the height of Michael Jordan, Yahoo! News reported.

"Even though he is short and I am tall, we have had similar struggles throughout our lives," Kosen told Yahoo! News. "When I look into Chandra's eyes, I can see he's a good man."

Kosen, 31, held the record for the largest hands on a living person -- from his wrist to middle finger was 11.22 inches. Dangi "is the same height as six cans of baked beans stacked on top of each other," the Daily Mail wrote in an article.

Their London meeting was set up as part of a celebration for the 10th annual Guinness World Records Day. Dangi, the shortest man the Guinness World Records team has ever measured, told reporters he felt honored to be included. "It's been a lifelong dream to travel, and becoming a Guinness World Records title holder has enabled me to do that," Dangi said.

Guinness World Records Day was created to recognize the date in 2004 when the "Guinness Book of World Records" became the bestselling copyright book. People try to set records during the 24-hour event because they're short-listed for the next year's book, according to the Guinness World Records site.

Other attempts Thursday included:

The Largest High Heel Replica Shoe Commercially Available, created by American fashion designer Kenneth Cole. Cole revealed the 73-inch bootie on the "Today" show Thursday morning, the New York Post reported.

The Most People Eating Breakfast in Bed, set by 388 people in China.

The Largest Gathering of People Dressed as Penguins, set by 373 people in penguin costumes in London. The penguins waddled for two kilometers to raise money for a local hospice, the Newham Recorder reported.

The Fastest 100-Meter Run on All Fours. The previous record-holder was trying to beat his own time, but a 19-year-old challenger took the prize. Katsumi Tamakoshi ran 100 meters in 15.86 seconds on his hands and feet, according to the Guinness World Records site.

The Most People Head-banging Simultaneously, set by 320 high schoolers in Australia.

The Longest Uninterrupted Live Weather Broadcast, an attempt by "Today" show weatherman Al Roker. He must broadcast for 34 hours to set the record. He began the report at 10:05 p.m. Wednesday and will keep going until 8 a.m. Friday -- and all he can talk about is the weather for last week and next week. Live stream here.
