BadIdeas are things you JUST SHOULDN'T DO!, generally because the consequences are obviously bad!

• Someone told you to “rm -rf /”? It's probably a BadIdea.
• You found a candy bar on the footpath and want to eat it? Chances are it's a BadIdea.
• You want to see what would happen if you put your finger in your RJ45 crimper? You guessed it, BadIdea.
• You can't be bothered to sort out dependenciess for an RPM you're trying to install and add --force to the CommandLine, because someone said it would solve your problems? Generally a BadIdea!

Play it safe kids. JUST (DON'T) DO IT!
