stealthy and naked

Yesterday, Charlie was sneaking about the house, buck-naked. I told him to go get some clothes on. He said, "But I'm inbisible."

"Charlie, you're naked. Go get clothes on," I repeat

"You tan't see me, Im inbisible," he insists.

I counter that with, "But I can see your skin."

"My tin is inbisible," he counters. "Clothes is not inbisible."
