Laughter is Contagious...Unfortunately

I've learned that hard way how difficult it is not to laugh when certain comical events take place in the classroom. Depending on the classroom environment, the inter-social system present between the students' homes, the goofiness of the teacher, and the mastery of comedy possessed by the students, sometimes all that is necessary to create a moment of overwhelming hilarity is for someone to laugh. The following is proof that a child's ability to make others fall out in hysterics starts very, very early.
