A
couple of good stories

Procedure:
1)
Show students a picture of two people. (Not too outlandish ones.)
Projection via OHP works fine. Tell students that you know the
people in the picture very well and are willing to answer questions
about them.
2)
As students keep asking questions make up your answers but be
consistent. Occasionally throw in an unusual bit of information,
e.g. Why they moved back to London? Well, they wanted to be closer
to their son, who was in prison at the time. After about 5-10
minutes declare that you do not really know the people but just
made up the whole story.
3)
Now pair students and ask them to decide which one in their pair
is A and which one is B. A gets a picture and has to pretend to
know the people in it. B has to ask questions and keep asking.
The more insistenly the better.
4)
When the picture seems to have been exhausted, hand out the second
picture, this time to student B. Repeat the process. Sometimes
students will want to go on and talk about a third picture. It
would be good to have a few at hand so that you can keep everybody
talking.
