A mother takes her three sons to enroll in school. The teacher asks.
Teacher: What are your sons names?
Lady: This boys name is Leroy, this other boys name is Leroy, and Leroy here is my third sons name.
Teacher: Isnt it confusing having all three boys named the same?
Lady: Oh no, you see when its time for lunch I just holler out the door, Leroy! its time for lunch, and they all come a runnin. When its time for dinner I just holler out the door, Leroy! its time for dinner and they all come a runnin.
Teacher: Ok, so what do you do when you want a specific boy?
Lady: Oh, well then I just holler out their last name.
