When you're out fishing, you're probably more concerned with just hanging out with your buddies and having a good time than your are with actually catching any fish. But if you've got one person in your group who takes the actually fishing element of fishing (the boring part) waaaaaay too seriously, try pulling this prank on them! They do have to have a long pole, but if they do all you have to do is quickly tap the end of their pole, which should wiggle it enough to make them think they have a bite, haul frantically, get nothing, and become saddened while you laugh behind their back. No setup, no tools, no chance for lawsuits. Great prank.
