Blinky, you’ve got to be kidding. But the fact that you don’t know who Lois Lane is only indicates how frum / temimusdik you really are (which is a good thing!) as opposed to us older folks who grew up on television and movies in our early days (but have since repented!)
In a nutshell, Lois knew (suspected?) the true indentity of Clark Kent / Superman (but you probably don’t know them either.. just as well I suppose!)
