Myopia: cow orkers and هؤلاء السمجين

Have you ever read a word wrongly? Or just gave it another meaning?
My eyes, or is it my brain, plays tricks on me, but I am thankful that I am not the only one, am I?
The word coworkers was written without the hyphen I am used to and I read cow orkers and wondered if that was another breed of cowboys.
On the Arabic section I tripped into a post that was full of name calling, so I just retreated and continued to hunt for another post. Then I saw a post by my friend Mohamed Almurtadha. Ahhh this got to be good, but then I read the title هؤلاء السمجين
What???? Was the name calling contagious, to the extent that the word سمجين appeared on the title of the post?
Of course not, he wrote السمحين but my visit to that other post caused my myopia. The ha`a became a geem.
Please tell me that I am not the only one.
