Conversation with my Dad at 6am..

Him: What are you doing?
Me: Cutting celery
Him: Why?
Me: For breakfast
Him: What? You've got to be kidding!
Me: For the rabbits breakfast
Him: But they can't eat lettuce!
Me: It's celery
Him: Celery is the same as lettuce
Me: No it's not
Him: Then why are they both green?
