Pencil in England

"Where's your pencil, Bud?" the teacher asked an American boy who had just come to school in Britain.

- I ain't got one, Sir.

- You're in England now, Bud. Not ain't, haven't. I haven't got a pencil. You haven't got a pencil. They haven't got a pencil.

- Gee! Pop said things were tough in this country, but I didn't know pencils were so hard to come by.
