Sherlock Holmes and Dr Watson go on a camping trip in the countryside.
Late at night, Holmes and Watson are lying on their backs looking up at all the stars in the sky.
Sherlock Holmes says, 'Doctor Watson, look at all the stars and tell me what important question we have to ask.'
Doctor Watson says, 'Well, OK. There are millions and millions of stars in the sky.'
'No-one knows exactly how many.'
'There are planets out there that no-one has seen with a telescope.'
'Maybe there is a planet somewhere that is just like Earth.'
'I think the question we have to ask is, “Is there life in another part of our universe?”'
And Sherlock Holmes says, 'Watson, you idiot!'
'The question we have to ask is “WHERE IS OUR TENT?!”'
