Many, many years ago, outside the local KFC my mate threatened a gang of yobs with an air gun that I had in my van. We were in my van eating KFC after the pub turned out and they started throwing their half eaten chicken legs and a box of chips at my van. My mate was ****ed. He got out with the gun, held it to one of their heads and threatened to shoot him! His mates all legged it, my mate gave him a kick up the arse, he legged it, we laughed about it, finished our KFC and drove off. We got to the end of East Ham High Street to find it blocked by a police car. We thought there was an accident. Other police cars screeched up and dragged us out of the van. Of course, they found the gun and chucked us in the cells while they were trying to find them (they had phoned in). They couldn't find them so they let us go about 4.00 in the morning but kept my gun.
That was over 45 years ago but whenever we bump into each other every few years, it's always the same. One of us will recreate the 'arrest'.
"Where's the Gun?"
"What gun?"
"Found it!"
We still have a laugh about it. I bet it wouldn't be so funny these days though!
