Superman is called to an incident where a man is trapped in an extensive building fire.
Rescue authorities tell Superman that they can't do a thing to help and that his superpowers are the only thing that can save him.
"Heck" cries Superman "its my day off and I've got to catch up on my house cleaning."
The authorities look aghast at him and demand he do something.
"Okay" relents the caped wonder. So he wonders over to the building entrance, looks up and yells "use a fire extinguisher you moron!"
