Sarah has learned about knock knock jokes and such from school. So Robert, Sarah and I were sitting around exchanging various riddles resulting in much laughter, but none brought about as much laughter as THIS:
Me: Why did the chicken cross the road?
Me: To get to the other side!
Sarah: *maniacal laughter*..
a minute later
Sarah: Why did the chicken cross the road?
Sarah: To get to the other side!
Robert and I: *giggles*
Sarah: And then a car hit him! *claps hands together*
