That's funny! When I was a junior in high school, the seniors let a pig loose in the school. Our senior prank, of which I was not part of!!!, was setting a bag full of crickets loose in the school. I think that it is expected that there be some kind of senior prank and as long as nobody (or animal) gets hurt, it is just good clean fun! Too much emphasis is placed on always doing the correct thing and if you don't cut loose sometimes, your head will explode!!!
