"What are their names?" he asked. 

"LeRoy, LeRoy, LeRoy, LeRoy, LeRoy, LeRoy, LeRoy, LeRoy, LeRoy, and LeRoy," she answered.

"And, what if you want them to come to the table for dinner?" 

"I just say, 'LeRoy, come eat your dinner'," she answered. 

"But what if you just want ONE of them to do something?" he asked. 

"Oh, that's easy!" she laughed, "I just use their last name!"
