A lot of funny stuff here!
Lemme try a couple:
"I hope you learned your lesson about this," Billy's dad said. "So, can you tell me what you learned today?"
Billy thought for a moment, then he finally said, "I was supposed to learn something? What are you talking about, Dad?"
"...So that's how your dad and I solved the mystery of the noise in the attic," Lisa's mother said.
Lisa, who had been picking a hole in the carpet, glanced up at her mother.
"I'm sorry, were you still talking to me?" she asked.
