Old story roony... but good nonetheless!
Cranwell, the College WO walked up to some hapless cadet (might have been me) and whispered in his ear:
"Have you heard about the German on the Station, sonny?"
"No, Sir" (cacking myself)
"Herr Barbers? HERR CUTZ???"
(Almost in tears): "Okay, Sir!"
Also heard on parade:
"Officer Cadet FOX!!!!"
"Yes Flt Sgt!"
(After a pause) "Are you as CUNNING as a fox?"
"Sometimes Flt Sgt!"
Guess you had to be there...
