Pot was upset one afternoon when she noticed that her Dad was not in the same room as her. We were watching Despicable Me then so staying in the living room was not an option to them.
So I explained to her that her father is in the kitchen, battling the roaches like a super hero.
Pot's eyes light up and said "Oh like Superman! Where is his costume with the panties, Mommy?"
Trust that kids have a way of noticing. So the next time that you have a liking to wear your underwear inside out, DON'T! They will notice.
