Fishing For Intelligence

(At this time we are having a “fishing derby” where kids can bring fish in and we will measure them. The three biggest fish that have been caught have their measurements on a board.)

Customer: “Are these fish measured in feet?”

Me: “No, they are measured in inches.”

Customer: “Are you sure?”

Me: “I’m positive considering the biggest according to the board would have to be 17 feet, and the only fish I can think of that can grow to be 17 feet long is a shark.”

Customer: “You have sharks in this lake?!”
