Two blonde sisters, Abby and Amy, go fishing and decide to rent a boat on a lake.

After fishing for hours at different spots and catching nothing, they decide to try one last time before giving up.

Suddenly, the fish start biting, and they catch their limit in less than twenty minutes.

Amy: “Hey, we should mark this spot so next time we’ll know where to fish.”

Abby: “Good idea.”

Abby pulls out a can of spray paint and paints a large X on the floor of the boat.

Amy: “Why did you do that?”

Abby: “Now anyone else who rents this boat will know where to fish.”
