I recall a true story (honest) when I were but a young drunken lad and somehow found myself in Sydney - I told my parents I was going to visit a friend in London, which I was, but returned 2 years later after a few detours.
Walking home one morning, after a night of alcohol and having had breakfast with a number of miscreants, en route to the hostel where I was staying I enountered Public Enemy coming out of their hotel (this was in 1990). Very unoriginally I asked Flavor Flav: "You got the time mate?" I am sure he must have been asked this a thousand times, but he looked at his wristwatch and said "yeh, it's <insert time as I can't remember>, you look like you should be in bed". He was right. But they stood and had a chat with me for a while, I think they were confused to find a hungover Scotsman in Australia who knew who they were.
(this story will only make sense if you realise who he is and what he wore around his neck)
