We were going somewhere the other day and I opened my iPod touch and B said, "is that a game? Oh, you're on Twitter." How does a 3 year know that?!
The other morning the kids were arguing about where a certain vegetable grew. B asked if it was true that it came from the sky. (His sister was mischieviously trying to mislead him...). I said, no it grows in the ground. He proceeds to say, "my hypothesis was correct!"
