[quote]This was yearsss ago, before I was even at my current school. On the last day, some of the people graduating pranked the teachers by releasing three pigs into the school, one had the number 1 on it, the second had the number 2 on it, and the third had the number 4 on it. So when the teachers got all three pigs they were still running around searching for one with a three on it.[/quote]
