Exoskeleton Upgrade

Sometimes when I’m changing my son’s diaper, I’ll pretend like he’s a robot or some futuristic mech-warrior.  I’ll tell him that his exoskeleton body armor is being upgraded to provide him better protection, as I strap the new diaper on him.  As I snap his onesie closed, I'll tell him that his force field is now activated.  He must believe me, because it’s usually about that time that he gets cocky and starts taunting me with raspberries.
