SOSL,
If you remember, several D.I.'s were allegedly posted to RAFC in a (Failed) attempt to make Sgt R. look intelligent.
Not difficult when , for example, Sgt R. was persuaded that the map of the hunting area for the Cranwell Beagling pack that was posted up in the Junior Mess was, in fact , a map of Arabia.
The response was almost predictable:
"Of course I knew that!'......... I was stationed there you know!......What you lot don't realise ..etc...etc...."
