This may be one of the best senior pranks I've ever heard, and mostly because it's so simple, and so good, yet I haven't ever heard of it before! [please note the celebrating seniors in front of the pissed off administrators.]
School officials tried to disguise it by panting it green, then painting a big 2014 over it... but they probably shoulda just let it be. Would it really be THAT noticeable if kids were sitting in chairs all over the field?!
Also... the other students in the school hate it. They're mad. They're planning to jump the pranksters.... probably disguised jealousy for not coming up with it themselves.
Side note: If your kids did this, would you be mad or proud?
