Is a familiar refrain, one I respond to regularly by pointing out that laws alone aren't enough.
There are, of course, other laws like the laws of physics or economics. Then there are the funny laws.
Anyhow I tumbled onto this list under the heading of this post when helping with a crossword.
As an aside, the crossword had already used Murphy's Law and Gresham's Law in clues, and then asked simply "Cole's Law?" (7,3,6,5). The answer I got as a variation of the one in the linked list is simply "cabbage and carrot salad."
