"This May 22, 2012, photo shows students loading bikes into a truck during an organized bike ride to Kenowa Hills High School in Walker, Mich. The 65 graduating students who participated thought they were having harmless fun but in the principal's mind they had broken the ""no pranks"" rule and suspended them. The strict edict eventually caused parents, students and even the town's mayor to ask: Where should schools draw the line? The principal later apologized.
