It is illegal to wake a sleeping fireman.

The Law Explained

In the town of Racine, a rather considerate (if odd) local rule theoretically made it a punishable offense to wake up a slumbering firefighter. This likely stemmed from an era when firemen lived at the station for long stretches and desperately needed unbroken rest between grueling emergency calls. Of course, the fire alarm itself is completely exempt from this rule.
