Two blonde sisters, Abby and Amy went fishing and decided to rent a boat on a lake. After fishing for hours at various spots and catching nothing, they decided to try one more time before calling it quits. Suddenly, fish started biting and they caught their limit inside of 20 minutes.
“Hey, we should mark this spot so next time we’ll know where to fish,” Amy said..
“Good idea,” Abby replied replied, taking out a can of spray paint and making a large X on the floor of the boat.
“Why’d you do that?” Amy asked.
“Now anyone else who rents this boat will know where to fish.”
