Knock Knock Stories

Our conversation as we drove across town last night:

Lizzy: "Knock knock."
Me: "Who's there?"
Lizzy: "Um.... Lexi."
Me: "Lexi who?"
Lizzy: "Um... Lexi Smarty Pants" (laughs hysterically... Lexi is not really amused).

This goes on for about five minutes. She won't stop telling these hilarious jokes.

Lizzy: "Knock knock"
Me: "Can we take a break from the jokes, Lizzy?"
Lizzy: "But Mom... my have LOTS of knock knock stories to tell you!"
