teenagers are never joking. when seeking to prove a point, principals and teachers should remember that teenagers are never, ever sarcasic or ironic. if they say "I wish someone would drop a bomb on this school right now," that means they have arranged for a nuclear arsenal to be emptied onto the school and should be immediately suspended and ridiculed. if they say they were merely coming up with a joking excuse to postpone a bio test, reply that all jokes are funny, and that since dropping a bomb on a school is not funny, it is therefore  not a joke.
