Many years ago, a group of us ending up playing a game of charades. It went along as these things usually do, until one chap started to do one and nobody had the slightest idea what was going on.
It's a film - five words - first word - sounds like...
He then repeatedly flung his arm to one side and brought his hand in front of his face, as a fist, then flicking the fingers and thumb out into a star shape, as fast as he could.
Nobody had the slightest idea what this was supposed to mean, but he could think of no other mime that he could do for any of the words, so he just continued, repeating this demonstration with increasing theatricality.
Eventually, we had to give in, largely due to people laughing themselves to incapacity, and ask him to reveal the film title.
Bridge on the River Kwai.
Apparently, the mime was a fridge door opening and the light coming on...
I still laugh about this forty years on.
