On that last point, I'm seriously considering creating a character named Losi, I've typed it so often.
That would be a delightfully confusing story. Which time did she mean Lois and which time did she mean Losi?
I haven't noticed any Claks pop up in a story, but I'd definitely point it out if I did.
Not in these stories, but back in my Superman Returns days, when my old laptop lost the "r" key... it was rough. Clak was everywhere, that dummy.
