Thanks to Clive for this one;
I asked a friend's little daughter what she wanted to be when she grew up.
She said she wanted to be Prime Minister some day.
Both her parents, Labour supporters, were standing there, so I asked her,
"If you were Prime Minister what would be the first thing you would do?"
Her parents beamed, and said, "Welcome to the Labour Party!"
"That's a worthy goal!" I told her, and continued, "But you don't have to wait until you're Prime Minister to do that. You can come over to my house, mow the lawn, pull weeds, sweep my drive and I'll pay you £25.
Then I'll take you over to that homeless chap who hangs out in front of the store. You can give him the £25 to use toward food."
She thought that over for a few seconds, then she looked me straight in the eye and asked, "Why doesn't the homeless man come over and do the work himself and you can just pay him the £25?"
