Cody:  (out of the blue)  Grown ups are boring.

Class:  (coming to my defense)  You just called Mrs. B boring.  That's breaking rule number one!  RESPECT!  Yeah, she's not boring!  That's just mean...

Mrs. B:  (acting like I'm going to defend Cody)  Come on, guys!  To be fair, we all know that only boring people call other people boring.

Cody:  (looking smug)  YEAH!  (lightbulb)  HEY, wait a minute!

(Raucous laughter ensues.  A minute passes and everyone settles back into work.)

Cody:  (to me)  That was a good one.
