"This is the hole my son will chew on, so it's only natural for me, as his father, to inspect it. You can tell right away if an XX has been picking up and eating just any P."

"I have absolutely never done anything like that."

"Then you can easily show me, right?"

"Ah, th-that..."

"You're not lying to this old man, are you?"

"N-no, absolutely not!"

"Just for a moment, you're only going to look?"

"Yes, just for a moment."

"I knew this would happen. Damn... Why is the XX color like this?"
