One promising concept that I came up with right away was that you could
manufacture personal air bags, then get a law passed requiring that
they be installed on congressmen to keep them from taking trips. Let's
say your congressman was trying to travel to Paris to do a fact-finding
study on how the French government handles diseases transmitted by
sherbet. Just when he got to the plane, his mandatory air bag,
strapped around his waist, would inflate -- FWWAAAAAAPPPP -- thus
rendering him too large to fit through the plane door. It could also
be rigged to inflate whenever the congressman proposed a law. ("Mr.
Speaker, people ask me, why should October be designated as Cuticle
Inspection Month? And I answer that FWWAAAAAAPPPP.") This would save
millions of dollars, so I have no doubt that the public would violently
support a law requiring airbags on congressmen. The problem is that
your potential market is very small: there are only around 500 members
of Congress, and some of them, such as House Speaker "Tip" O'Neil, are
already too large to fit on normal aircraft.
