A substitute enters a noisy classroom and asks the students to stop chatting. Upon sitting on his seat he realize that one of the students has put a farting cushion. Without thinking twice he decides to teach that student a stern lecture by voring him whole! The whole class is shocked as he is gobbled up. Then the substitute decides to do a lesson on the digestive tract. While speaking, the student trapped inside him will wiggle trying to escape but to no avail. Finally the substitute counts down from 10 and right when the bell rings the student desolves instantly. The class is dismissed and the substitute leaves a note for the teacher telling him he has dealt with the annoying student.
