At a Dorset airstation:
"Testing the tannoy from the main gate. 1,2,3,4,5,5,4,3,2,1 test complete"
This carried on for a fair while the lad was getting a bit tired of the repetition so tried to vary it
"Testing the tannoy from the main gate A,B,C,D,E,E, D, errrr 5,4,3,2,1 test complete"
The entire airstation collapsed with laughter.
We had some comics among the QMs/BMs on Zulu - whenever there was a pipe to be made that wasn't routine or mundane, one of them would stand a few feet from the microphone and = just as the other one was going to make the 'pipe' - he'd say something along the lines of "This'll cheer 'em up", "This'll go down like a lead parachute" or "Gawd, he's in deep".
