Superman...the untold stories

Me:  Owen.  You are cranky, you are being very disobedient today, and you couldn't sleep in the middle of the night last night.  You need a catnap.  There will be no arguing and no changing my mind.  You will take a catnap on my bed today while Asher is in his crib.
[Wailing and gnashing of teeth, mini-tantrum, defiance ensues.  Mom is set to win, and does.  Owen begins to accept inevitable and is sitting on my bed.]
Me:  Now, it's not so bad.  You do not have to take a real nap.  Just a catnap!  I will wake you up so you don't sleep too long and miss out on your day.  You are going to feel great when you wake up.  You're going to have so much energy and feel like superman!  Seriously great.
Owen:  [lighting up]  Will I have energy like Superman?  Will I be able to FLY? 
Me:  Well, you won't be able to fly, but you'll have tons of energy to play and feel happy until bedtime, and Superman also uses his energy to help people, not just to fly.
Owen:  He HELPS people?? [Neither of the children actually have a clue as to who Superman is, yet they are smitten with him for some reason.]
Me:  Oh yes, that is why he is so super.
Owen:  Are you telling me that Superman takes CATNAPS??
Me:  Of course!  How do you think he keeps up his energy for helping people?  He probably takes a catnap almost every day!  Just a short one!
Owen:  REALLY?
Me:  Oh yeah, no doubt about it.
Owen:  [smiling]  OK, mom.  I'll take a catnap.
[Mom closes door and peeks in mere minutes later and child has crashed and looks like an actual cherub on her pillow.  Mission accomplished!]
