We walked past the shelf with packaged underwear: "Wow, check out this underwear! Look at those ninja turtle ones! Look at those! (I can't remember exactly what the next design was)
Wait for it...
"Oh, look at THOSE! They have frozen characters on them! Mommy, aren't you so jealous? Aren't you jealous of those frozen underwear?!"
Yes buddy, yes I am. Sadly, they do not make Elsa and Anna underwear in mommy's size. No Olaf on my undies...
