I've posted this one before, but I think it's worth a 2nd showing.
Finningley 1975.
100 Airmen, post breakfast, walking to work down the main drag.
1 LAC minus beret.
SWO 'Johnny' Walker appears on Guardroom verandah.
"STAND STILL". 100 Airmen freeze.
"YOU, AIRMAN. WHERE'S YOUR HEADDRESS?" 99 Airmen breathe a sigh of relief.
In a quavering voice the young LAC replies "I don't have to wear it Sir. I have a chit".
"THEN WEAR THE F***ING CHIT THEN" bellows the SWO.
99 Airmen fall about laughing.
