Keep your canary's in check, please! In California, it's illegal to start whistling for a lost canary before 7 a.m. Citizens of Berkely must keep their canary whistling on mute before the sun is up.
What if you're whistling for some other reason? Well, no one knows. This law came to be when someone bothered the entire town of Berkely while he whistled for his pet canary to come home. They must have been pretty disgruntled.
