I saw a brief story about this in this morning's Chicago Sun-Times and I was so hoping to find a picture -- and I found this instead!
According to this story in the Columbus Dispatch, the author of this prank, one Kyle Garchar, of Hilliard, Ohio (a suburb of Columbus) was given a three day in-school suspension as a result of this stunt. Garchar and his accomplice/girlfriend, Danielle Jewell, were also "banned from school activities for the rest of the semester."
There are times when, as responsible adults, we must set our faces on grim and tsk-tsk gravely at a young person's behavior.
Of course, as soon as they leave the room, we can dissolve in hysterical laughter.
This is one of those times. (All the young people have left the room, right?)
I think this prank is extraordinarily creative and funny. But I'd never let that kid know I thought so....
