Cherry Yoshitake – aka Mr Cherry – has probably lost track of the number of Guinness World Records titles he’s achieved over the years!
His current records include Most marbles moved with chopsticks in one minute, Longest duration to spin a fidget spinner on the nose, Most baked beans eaten with chopsticks in one minute and Most sticky notes stuck on the body in 30 seconds.
However, the Japanese entertainer is most famous for being able to crack 115 walnuts with his bottom in one minute.

Guinness World Records recently visited Mr Cherry on the set of Officially Amazing Goes Bunkers to ask him for his tips.
