Most pranks suck and aren't very funny nowadays, this is not one of them. Love everything about this prank. The location being up north (I assume New England area) places you would never see an alligator makes it that much better. The last thing any of these people expect is an alligator swimming by or towards them. Which makes the initial reaction and fear so genuine. Don't get me wrong, you do this to someone down here and their going to freak and that's because you should assume ever fresh body of water has a gator in it. By the way swimming in a lake or pond is gross and that's even before you toss alligators in the mix. Pool or beach any day you savages.
