Definition: supposed law of nature, expressed in various humorous popular sayings, to the effect that anything that can go wrong will go wrong.
So if you watch the cartoon if should make more since, anyway It means something will go wrong sooner or later for example, a town lives by a sea, 2 months later a hurricane swings by and all the water from the ocean flooded the town. If you know any body paranoid saying O! that shed should be built some where else those trees can fall down any time. That would be an example. The murphy law is used in nature so it wont happen to any thing man made. Its sort of like Karma if you do something bad it will come back to you naturally or randomly.
Hope I helped:) Please request a new topic for my type show to night.
