Back in the 60's, I was involved in moving the computer centre at Melbourne Uni from one side of the campus to the other. In those days, the moving contractor would get his workers from the local Labour Exchange for about $5 per day & they tended to be pretty rough diamonds.
On this particular summers days the female students were all out in force in short shorts & tight tops etc & were causing quite a distraction to the movers. Finally, one of them stopped, pointed to a particularly gorgeous young thing and said:
"Get a look at the arse on that one. I'd bang that till I had a heart attack"
And his boss, in all seriousness shouted at him:
"Watch your fucking mouth!! She can fucking hear you!!"

I laughed so much I lost track of the cases I was supervising & I've never forgotten it to this day.
