Eric: "That's the public pool with the water slide..."
Jack: "Oh! A water slide!"
Eric: "And water cannons..."
Jack: "Water cannons! Well, I'll bet Evan's not all that interested in water slides and water cannons."
Eric: "No, I'm sure Evan has NO interest WHATSOEVER in water cannons."
Evan: "Daddy, that's a really boring joke, and grownups make it all the time."
