DO NOT BE AFRAID EARTHLINGS. WE INTEND YOU NO HARM. WE COME IN PEACE.
we currently have a death ray focussed on your puny and worthless planet.
Our timewarping inter-galactic spaceship, the USS Mondeo, has run out of power in orbit near your inconsequential little globe, and the lithium cells canae take it, captain (sorry, slipped into StarTrek speak there).
We urgently need fuel of a type which your planet cannot provide and does not even have a word for.
Our Geo-scientists have, however, discovered that an alternative does exist. It is a fine blend of tobacco, Theakstons Old Peculiar real Ale and those little pictures of the Queen you all carry in your wallets. We need massive quantities of each, or we will have no choice but to dissolve your planet in a nuclear fireball.
To save your ridiculous little species you need to send all the supplies of those three items you can muster, to us. We have hijacked the so-called hewittalan6 and the cash, beer and fags, Sorry, necessary supplies can be forwarded via the funny little envelope next to his name.
Finally, if any of you see that Stephen Speilberg geek, tell him if he makes us that ugly in his next film, we're gonna set fire to his beard.
Peace,
