What Kind of EEZ are you??

 
An American and a Japanese were sitting on the plane on the way to LA when the American turned to the Japanese and asked:
"What kind of -ese are you?" 

The Japanese confused, replied: "Sorry but I don't understand what you mean."
The American repeated: "What kind of -ese are you?" 
Again, the Japanese was confused over the question. The American, now irritated, then yelled: "What kind of -ese are you ...
"Are you a Chinese, Japanese, Vietnamese!, etc......???"

The Japanese then replied, "Oh, I am a Japanese." A while later the Japanese turned to the American and asked What kind of "-key" was he. 

The American, frustrated, yelled, "What do you mean what kind of '-kee' am I?!"

The Japanese said maliciously, "Are you a Yankee, donkee, or monkee?"
