My Kid Gets Meta-Jokes!

So, if you read my wife's blog, you know that Liz now understands sarcasm. If you know me, you know I was proud of my girl. Well, tonight at dinner:

Liz: Dad, why did the duck cross the road?
Me: I don't know.
Liz: Because the chicken was on vacation...See, that's funny because the joke is usually about chickens...

My heart swelled.
