As luck would have it I was given a great opportunity to use it again today.
I was at a training session on mentoring when the trainer was explaining how our brains don't always have the answer when needed. He said, " It's like when you're in the pub and someone asks who sang a song, it's on the tip of your tounge, but you can't remember, then at 2 in the morning it comes into your head."
So I said "I've one of them at the moment, who sang Tiger Feet?".
Cue 10 people blurting out "mud!" within 1 second of me asking.
You can guess the rest...
