On stupid emails

I recently got an email that reads like this:

"Can you raed tihs? Olny 21 plepoe can. I cdnuolt blveiee taht I cluod aulaclty uesdnatnrd waht I was rdanieg. The phaonmneal pweor of the hmuan mnid, aoccdrnig to a rscheearch at Cmabrigde Uinervtisy, it dseno't mtaetr in waht oerdr the ltteres in a wrod are, the olny
iproamtnt tihng is taht the frsit and lsat ltteer be in the rghit pclae. The rset can be a taotl mses and you can sitll raed it whotuit a pboerlm. Tihs is bcuseae the huamn mnid deos not raed ervey lteter by istlef, but the wrod as a wlohe. Azanmig huh? yaeh and I awlyas tghout slpeling was ipmorantt! if you can raed tihs forwrad it.

ONLY FORWARD IF YOU CAN READ THIS"

Okay, I've gotten an email with this text before and found it quite amusing. It is funny that you can still read it, even though the words are all horribly (if purposely) misspelled. But it's the first and last lines that are pissing me off so badly. If the whole point of the study (which may or may not actually have existed) is that "the human mind works in such wonderfully wonderful ways that you can read this text regardless of how misspelled it is" (paraphrased) then why does it also say that only 21 people can read it? I imagine they meant, like one in 20 or 21 or maybe even in some weird world 1 in 2, but it still seems like the numbers are ridiculously skewed, which makes me skeptical that such a study every existed, or if someone just made this up. And my issue with the last sentence is this: if you can't read it, would you actually forward it? If you would, then you should be shot, maybe not in a place that would kill you, but definitely in the leg or something, because that's just dumb. Would anyone in the world actually think, "I have no idea what this says, I'm going to forward it on to my entire list of contacts in the hopes that it will make sense to one of them."? I doubt it. It's just silly.

Sorry, I guess I'm in that kind of mood today.
