Overheard from my 10-year-old nephews:
Abe: Why does Jacinta read 100 books at a time?
Trent: I don't know. Why?
Abe: No, I was actually wondering why.
Trent: Oh, I thought you were setting up a joke.
Abe: Oh, okay. Why does Jacinta read 100 books at a time?
Trent: I don't know. Why?
Abe: Because she's a HUGE NERD!
Kid thinks he's got jokes!
