From Letters Live:

In December 1997, as a result of an official complaint from a neighbour, a Michigan resident named Stephen Tvedten received, indirectly, a stern warning from the region’s Department of Environmental Quality in the form of a letter – a letter in which he was given six weeks to remove two “unauthorized” and “hazardous” dams from the stream on his property or else face prosecution. Tvedten’s amusing response soon made the local news. The case was quickly dropped.

Peter Dinklage joined us at Letters Live at The Town Hall, NYC to read this hilarious letter.
