Sometimes I "test" my kids by intentionally advocating a point of view contrary to what I've taught them, just to see what they say.

Today we saw Elmo on TV singing about the joys of getting dressed, but Elmo had no clothes on.
"Hey, Elmo's naked!" I said.
"No he's not," insisted the kids, "he's wearing his fur!"
"Yeah, but he has no clothes on!"
Princess rolled her eyes and said "He's just a puppet!"

Thank you. My work here is done.
