Craic

A sound engineer was concerned that his wife was going deaf. 

He consulted his doctor who suggested that he go home and ask his wife a question, starting at 40 feet and getting 10 feet nearer until she could hear him.
He went home and stopped at the front door, "What's for tea tonight dear?" he said.  Nothing came back. 

He moved another 10 feet closer to the lounge door, 30 feet, and asked again, "What's for tea tonight dear?" 

Still nothing so he went to the dining room door, "What's for tea tonight dear?" She must be really deaf he thought as he walked to the kitchen door, just 10 feet from her. "What's for tea tonight dear?" 
She replied, "For the fourth time, it's chicken!"
