When Funny Fred left school, he wanted to be a clown and to have his own business.

He decided to leave the UK and to live abroad - he moved to the USA. What did he do there? He went to circus school to learn about acrobatics and magic tricks. He also learned to play the drums. When he finished school, he learned two foreign languages - French and Italian. Then he opened his own circus schools in the UK, France and Italy. Now he has a big business. Funny Fred often visits children's hospitals too. He wears his clown clothes because he wants the children to have fun and get better quickly!
