I've never heard that version.  As I try to follow these stories, I think
it is apocryphal.  Although a lot of stupid laws do get passed that way.

I remember _The Mathematical Intelligencer_ running an article not too long
ago with a discussion of the aborted Indiana attempt.  One half of the
legislature mindlessly passed the law that someone introduced to please his
friend, whose geometrical description was so inept that no one could derive
a value of pi from it.  The other half failed to pass it, barely, but only
because the newspapers heard about it and had a field day.  Seems a free
press IS needed to control our legislators.  :-)  He also mentioned an
existing German law describing how to tax car engines that, if read literally,
implied an erroneous method for finding the volume of a cylinder and hence for
pi.  Surprisingly, it gives a smaller tax this way.  Perhaps that is why no
one is clamoring to get the right value in.

A weird book on pi with a long description of the Indiana fiasco is Petr
Beckmann _A History of Pi_.
