Hidden treasures in Kindergarten

I just love Kindergarten sometimes. You can never anticipate what will happen next.
Today, I was directing a reading group and noticed that one of the girls would not sit down. I asked her to sit. She attempted (painfully) but then sprung back up.
"What's going on?" I asked.
"Nothing," she said.
But by then, I had figured out that a whole lot of "not nothing" was going on. Her butt was sticking out about a mile.
"What do you have in your pants?" I asked.
"Nothing," she said, starting to blush a little.
"Are you going to show me or am I going to have to look?" I asked, unsure of what I would do if she didn't voluntarily show me the contraband.
So, she reached down inside her underware, and I had a brief seize of panic when I considered that maybe it was a colostomy bag or something, but then, she pulled out a watch. Then a plastic horse. Then a miniature Barbie. She had a whole collection of McDonald's toys jammed in there.
I just looked at her, shocked and unsure of what even to say.
"I'll put these in my backpack," she said, breaking the silence.
I nodded, swallowed, and replied, "I think that would be a good idea..."
