Kid: "Do I even want to know what a "John boat" is? Is that what they call a boat that smells like..."

Dad: "...rotten fish?"

Kid: "Sure, good save on the language mom doesn't approve of, Dad!"

Dad: "It gave in to pier pressure." 

Kid: "Just like I do, or so you say."

Dad: "It's a play on words, a pun, if you will."

Kid: "Do dads feel peer pressure to tell bad jokes?"

Dad: *sigh*
