Re: Mars Bar
I volunteered taking foreign students on a tour of Edinburgh, and they went on about stupid and unhealthy Scots eating deep fried Mars Bars. I stated we don't, so they went into the nearest chippy about bought one. They loved it and asked if I wanted a taste; I did not.
They asked me when Edinburgh Castle was built and I didn't know, but they were getting on my tits by then so I made something up. "It was in fact the original Strasbourg Castle, but the Scottish king loved it so much he bought it and had it shipped stone by stone to Edinburgh."
That'll teach them.
