When you think about it, even tho the prank aspect is all "Kid", it is amazing to see THAT many teenagers get together to pull such a stunt and not damage anything, or ...... screw it up.
It took:
Organizational skills
Team work
Discipline (To keep it harmless)
Creativity
Artistic Skills (They were ALL acting)
all the skills you need pull something off well in the work a day world, and have fun doing it too.
As an adult in the position of having to punish them, I would have a hard time keeping a straight face.
It should be turned into a class project!
