PINs

As I carefully sheilded my PIN entry from prying eyes at the automatic teller machine this morning, my partner quietly leaned over and informed me that she already knew what it was! "I do this all the time, not just because you're here," I explained, before launching into a PIN safety talk.
And talking about PIN safety - did you hear about the inflatible boy who took a pin to his inflatible school, and his inflatible headmaster told him "you've not only let me down, you've let yourself down and you've let the whole school down!" (Boom boom - as Basil Brush - and nephew Patrick who told us this joke - would say.)
