     A man with two badly burning ears went to see  
his doctor. "What has happened with you?" asked
the doctor. "Well, my wife was ironing while   
I am watching the ball game on TV. She put       
the hot iron near the telephone where my phone 
rang. I picked up the iron instead the phone."  
The doctor nodded, "And what has happened to  
other ear?" The man said, "I have just hung up
when a same man called again." The doctor      
couldn't help laugh when he heard this.         		1_______
