That's the same song, second verse.
Check how many posts (in this thread and others) say something like, "Double check!!" as if the simple checking to be sure it's unloaded is all that's required before they then point the gun at something stupid and pull the trigger.
It doesn't matter how many times you've checked it, or how thoroughly: the other three rules still apply.
People treat Rule One as if it means "All guns are loaded (until you've checked the gun, then you can do something stupid with it)." That's not what it means, as a certain number of numbnuts find out all on their own every year.
