Eli is getting undressed for the evening. He fights out of his shirt and t-shirt, then sits on his bedroom floor to wiggle out of his pants. Now he is looking down past his little white pot belly at his tighty-whiteys.
He stands up to inspect the situation further. He pulls out the waistband to discover another waistband underneath.
"Ooh, I have on two underwears."
Sometimes he forgets to take off the old underwear before he puts on the new underwear. One time he actually tried to put on the new underwear before taking off his pajamas. He's thoughtful that way, in that he's thinking about other things. He and I are a lot alike.
