my last year of high school me and about 5-6 other guys Flipped an entire class room...everyhting was upside down and on the oppositte side that it was on before hand... when everyhting was done we then spider webbed the whole room with about 600 feet of yarn we used duct tape to hold the string up...one of the kids went out side an filmed the teacher walk in and say " WHAT THE FUCK" from the window. luckily the teacher was pretty chill about it after wards and only the reaction he had was for us to take 100 question pop quiz and only gave us 30 min to take it.... we all failed it pretty bad....

good times!!!!
