A couple from a circus go to an adoption agency, but social workers are doubtful about their accommodation.
So they produce photos of their 15 metre long caravan, the back half of which is a beautifully equipped nursery.
The social workers then are doubtful about the education that would be provided.
"We've employed an Oxford don who'll teach the child all the subjects along with Mandarin and ICT skills".
There are then doubts expressed about the child’s healthy upbringing.
"Our full time nanny is an expert in paediatric welfare and diet", they reply.
So the social workers are finally satisfied, and ask what age of child they were looking for.
"It doesn't really matter", they say, "as long as he fits in the cannon".
