In a time when the whole earth has been explored and we have 24hr realtime contact across the planet I find it facinating when things like this have been lying there for centuries oblivious to the history playing out above them.

"pulling your legs'' comes from when people where hanged, the death was not quick, so your friends would pull your legs to kill you quicker.
I think this begs a question. Where did,'Pull the other one, it's got bells on.' Come from?The legendary jester executions of AD1296 perhaps.
Or maybe it's from the 1642 morris dancer pogrom.

The Sun consumes about 600 million tons of hydrogen..... Per second !
And at that rate it will still be a very long time before it runs out. It may only take a photon 8 minutes to get from the suns surface to the earth, but it might take 100,000 years for the photon to make it from fusion in the core to the surface in the first place.

Rudolf Abel, the notorious Soviet spy featured in the film 'Bridge of Spies'. Was originally called William Fisher, born on Tyneside, and never left the UK until he was 18.
True, but his parents were Russian and friendly with Lenin before Abel was born so there was some influence there!Bonefish Blues said:
