Leroy!!!!!

A woman walks into the downtown welfare office, trailed by 15 kids.
"Wow," the social worker exclaims, "Are they all yours?!?"
"Yep, they are all mine," the flustered momma sighs, having heard that question a thousand times before. She says, "Sit down Leroy." All the children rush to find seats.

"Well," says the social worker, "then you must be here to sign up. I'll need all your children's names."
"This one's my oldest: his name is Leroy."
"OK, and who's next?"
"Well, this one, he is Leroy, also."
The social worker raises an eyebrow but continues. One by one, through the oldest four, all boys, all are named Leroy. Then she is introduced to the eldest girl, named Leigh Roy!
"All right..." says the caseworker, "I'm seeing a pattern here. Are they all named Leroy?"
Their Momma replied, "Well, yes -- it makes it easier. When it is time to get them out of bed and ready for school, I yell, 'Leroy!' An' when it's time for dinner, I just yell 'Leroy!' an' they all comes a runnin.' An 'if I need to stop the kid who's running into the street, I just yell 'Leroy' and all of them stop. It's the smartest idea I ever had, namin' them all Leroy."
The social worker thinks this over for a bit and agrees, but then she wrinkles her forehead and says tentatively, "But what if you just want one kid to come, and not the whole bunch?"
"Oh, then I call them by their last names."
