When I left school, I got a job in the local cinema to earn a few pounds before starting my 'proper job' in the autumn. One week they showed the new Dr Who film "Daleks - Invasion Earth 2150 AD" - of course it was school summer holidays so the place was overrun with screaming children shouting "Exterminate, exterminate" every chance they got and we poor workers had to suffer through seventeen showings of the film not to mention endless sales of ice cream.
Many years later, they showed that film on television and I watched it with one of my nephews. I realised two things about it. Firstly, after thirty years or so, Dr Who (played by Peter Cushing) still had different colour socks on when he was outside the Tardis from those he was wearing when he stepped inside. Being an usherette teaches you a lot about continuity, i.e. there often is none. Well either that or socks are made from a tear in the fabric of the universe, which might explain why there's always an odd one. And secondly, I still knew all the words!
The Hubble Telescope has just picked up a sound from a fraction of a second before the Big Bang. The sound was "Uh oh".
