Why did the chicken cross the road?

A couple of days ago we were driving somewhere and Caroline and Carter were telling jokes to each other.

Caroline: Why did the chicken cross the playground?
Carter: why?
Caroline: To get to the other slide!
Carter: The playground had two slides?
Caroline: Yep, and the chicken got to play on both of them.
Carter: I want to go to that playground and go on both slides
Caroline: Me too.

I never thought that joke was that funny until I heard them tell it!
