What would be a good law we haven't already heard of?

“All laws, including this one, shall be illegal.”

A law that says ‘no more laws’.
In fact, a law that wipes out all other laws so we can start over.

Child molesters should have “I am a child molester” tattooed across their foreheads before being jailed. Life terms, no parole ever.

People who stupidly open unknown attachments and get a highly publicized virus in a school or business system even though there are signs everywhere saying “Don’t open unknown attachments!” should be laughed at, then whacked across the head with the CPU.

People who don’t take their screaming, talkative, or otherwise annoying children out of a movie theater, restaraunt, church, or other public place should be locked in a closet with said child and banned from the public place for a month. Second offense, banned for a year, third offense, banned for life and another head-whack with a CPU.
