Since I'm probably one of the chief "offenders" at finding this funny, I think that I should reinsert myself into the debate, although I may be too late.
I still think this is funny, for pretty much the same reasons that I find "The Three Stooges" or "Home Alone" funny. Everyone knows what it's like to hurt themselves accidentally, and I think that a large part of the appeal of physical comedy is the "thank god that's not me" factor. I'm sure everyone one here has either been party to or observed the old "the word 'gullible' isn't in the dictionary" joke (actually, it's being removed from the English version because it's actually a French word that's going to be replaced by 'freedom belief' or something

). The joke is only funny because anyone can fall for it.
Do I feel sorry for these women? Absolutely. At the same time, do I feel sorry for the guy that calls the police to report that his 50 lbs of pot just got stolen? Absolutely. Or the genius that tried to hold up a gun store full of cops? Sure. Does that stop me from laughing at their stupidity? No. These women were victimized and the guy needs to be punished, but there comes a point where you have to allow yourself to be amused by the idiocy that is this world.
Thanks to fark, here are some examples of other everyday stupidity that does have a humorous aspect.

Should I feel sorry for the two cops who shot each other accidentally? Sure. But it's pretty funny.

This poor woman was denied entry to a bar because of her fake arm. That could be used as a weapon. She was discriminated against because of her disability, to humorous results.

How about the Iraqi insurgents who mistakenly called an Army interpreter to tell him that they were on their way over to attack the Americans? Not so much, but that's because I'm an American myself.
