spell check, anyone?

Ok, just had to ask this: Why does the blogger spell checker suggest the word "Josef" in place of the word "Cosby"? And then "blocker" for "blogger"? what is wrong with this picture?

Oh, the insanities when one tries to use spell check. I don't very often, but with the previous post and my use of "feat" I felt compelled to at least attempt correct spelling once in a while.
