Marty is not happy. As a clownfish(小丑鱼), he feels like he must be funny.But he is not funny at all. He is very serious. So he decides to tell jokes to others.
He tells jokes to the lionfish, but they don't laugh(笑). He tells jokes to the tigerfish, but they don't laugh either(也).
"I am a clownfish, and I must be funny,"Marty says to his friend, a catfish.
"You don't have to be funny,"says the catfish."You do well in swimming.You are friendly and clever."
"But clowns make people laugh, so a clownfish must make fish laugh,"says Marty.
"The lionfish do not act like lions. The dogfish do not act like dogs,"the catfish tells him."Marty, just be yourself."
So, Marty does just that. He stops telling jokes. Soon, the other fish all like him. It makes him happy.
