I got into work at Lyneham and was asked to go and see the boss.
"You play golf don't you AR1?"
"Yes Sir, sort of"
"And you were on duty at the weekend - right?"
"Yes Sir I was"
"Well can you explain why a golf ball came through my office window?"
" No Sir I can't. I was on duty, I do play golf - But I've never done it in the dark"
"What??"
"I was on nights Sir"
