"Lois, I have something important to tell you."
"Sure, Clark. What is it?"
"Well - I used to be Superman."
"WHAT? Wait a minute? 'Used to be?' What does that mean?"
"It means I've given up being Superman to be Clark Kent to you all the time."

"Are you telling me that
I'm the reason there's no more Superman around? Gaah! I'm gonna kill you! Then I'm gonna clone you and kill all your clones!"
(That last line is brazenly stolen from the move "Madagascar.")
Well, Clark, it looks like you're up against it, old son. And I doubt that Lois is willing to give you any slack at all.
Have fun being clobbered 24/7/365.
