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.
