Size matters

[retired]

A married couple who are circus performers wish to adopt a child.
When they go to the adoption agency the agency questions the living conditions for a child in a traveling circus.
The couple takes out photos of their state of the art, luxurious 45' motor home.
The agency still has concerns about the child's education but the couple tells them the circus travels with tutors who in addition to standard courses, teach Spanish, French and Computer Courses.
The agency also questions about medical care for the child and the couple advises them that the circus travels with a doctor and nurses.
This satisfies the agency and they ask what age child does the couple want.
The couple answers,

"The age doesn't matter as long as the kid fits in the cannon."
