A lady walks into the welfare office, trailed by 15 kids...

WOW," the social worker exclaims, "Are they ALL YOURS???"

"Yes, they're all mine," the tired momma sighs, having heard that
question a thousand times before.

Well," says the social worker, "then you must be here to sign up. I'll
need all their names.

"This one is my oldest--he's Leroy." "OK, and who's next?" "Well, this
one's Leroy, also."

The social worker raises an eyebrow but continues. One by one, through
the oldest four, all boys, all named Leroy. Then she is introduced to the
eldest girl, also named Leroy!

All right...I'm seeing a pattern here...Are they ALL named Leroy?" Well,
yes--it's actually really convenient. When it's time for dinner, I just
yell 'Leroy!' and they all come running. And if I need to stop the kid
who's running into the street, I just yell 'Leroy' and the kid, whoever
he is, stops in his tracks. It's the smartest idea I ever had, naming
them all Leroy."

The social worker thinks this over for a bit, then wrinkles her forehead
and says tentatively, "But what if you just want ONE kid to come, and not
the whole bunch?"

Ah, that's easy," said the mother "Then I call them by their last names."
