Time Machine.
Barak Obama and David Cameron are shown a time machine which can see
100 years into the future.
They both decide to test it by asking a question each.
Obama goes first.
“What will the USA be like in 100 years time he asks?”
The machine whirs and beeps and goes into action and gives him a printout, he reads it out
"The country is in good hands under the new president, crime is non-existent,
there is no conflict, the economy is healthy. There are no worries”
David thinks “It's not bad this time machine, I'll have a bit of that” so he asks:
“What will the U.K. be like in 100 years time?”
The machine whirs and beeps and goes into action, and he gets a printout.
But he just stares at it.
“Come on David” says Barak, “What does it say”
David replies,
“B*ggered if I know! It's all in Arabic!”
