The Joke's on Me

A conversation with Savvy on the way home from grocery shopping:

Savvy:  "Mom, wanna hear a joke?"

Me:  "Sure."

Savvy:  "Okay.  Why is Rudolph's nose red?"

Me:  "I don't know, why is it red?"

Savvy:  "Cause Vixon punched him in the nose."

Me:  "Ha!"  (Hey, it's a kid.  You always laugh at the jokes, no matter if they make no sense.) 

Savvy:  "Don't laugh!" (in an indignant voice)

Me:  "Why not?"

Savvy:  "Cause it's not funny."

Me:  "Well, why did you tell me a not funny joke?"

Savvy:  "That's the point.  It was in this Christmas joke book.  How did it get in the joke book?  It's not funny at all.  You shouldn't laugh at stuff that's not funny.  That's a lesson."
