There’s the famous false story of the state that tried to redefine the fundamental mathematical constant pi to 3, but of course no one would ever be that stupid. Though, in Indiana in 1897, they tried to pass a law setting it at 3.2, which is only 0.2 less retarded.
House Bill 246 in the Indiana House of Representatives, introduced by representative T. Record, offered three different numbers to replace the "confusing" value of pi. Because nothing simplifies things like offering three different values for a fundamental constant. The bill was first seen by the Committee on Swamp Lands, then the Committee for Education and then the Committee for Temperance – possibly as the legislative system attempted to find someone dumb enough to deal with it.

Since the (evidently) extremely influential Committee on Swamp Lands saw no issue with the new definition, the bill actually had a chance of passing until, thankfully, a mathematician just happened to wander into the building on other business and, after checking the bill out, effectively informed those present that he wouldn’t wipe his ass with the bill for fear it would miscount the number of cheeks.
