Class has begun and the nun/teacher instructs the class to begin their note taking and study session quietly. However, Mary has other intentions... While the teacher is busy grading papers, Mary grabs a balloon from her bookbag and begins to blow. Anytime the teacher looks up she quickly hides the balloon. Mary blows to pop the first balloon and quickly pretends she doesn't know what happened. The teacher yells at the class after each balloon busting interruption and gets more furious! Mary pretends to be innocent, chiming in and acting concerned about the interruptions that have been happening in class. Mary blows up the next balloon until it gets nice and tight and then ties it off. She wraps her legs around it under her desk. She gets such a mischievous grin as she teases the balloon, squeezing it with her legs, and then giving it a poke! The balloon bursting interruptions continue. Mary blows to pop 3 balloons and leg squeezes/nail pops 2 of the balloons. Mary busts a total of 5 14"crystal balloons until getting caught by the teacher! The teacher scolds Mary and tells her to go to the priest's office.
