Woman goes to the Social Services and is asked to fill in a form with all her ten children's names.
"Ms. Jamieson, I can't help but notice but you've put down Jamie ten times though you have given me their sex. Surely you don't have children with the same name?"
"I do, they're all called Jamie. It makes calling them in for mealtimes very easy."
"But what do you do when you need just one of them?"
