The Dolphin  
 
Suddenly a dolphin comes along and you immediately think of Flipper. Like you are still a child, you start to wave at him. The dolphin gets angry and asks: Do I know you? You're a little frightened by its tone and say: Aren't you the great Flipper?The dolphin says: Is this a joke? Do you want to insult me? Go away and leave me alone. Not every dolphin is called Flipper! What do you say?

Sorry Mr.Dolphin, I'll go away now.

or:

Well, you're a smart dolphin, huh? Well then explain the fin on your back. Flipper has it too. Anyway, goodbye Flipper!
