Here is one of 99 things you can do with a lobster. The reason the lobster is in the classroom is because there is testing that day, and he brought it in to distract the teacher by pinching him. The lobster's name is Big Boy. The guy's name is Mac. He is telling the lobster his very important instructions. First, we hear the teacher tell everyone to take their pencils out. Then, the teacher writing on the paper. And suddenly, a horrible, blood-curdling screech broke the silence.
It may not make sense, but the room smelled of cow. Figure that one out. Especially since it was in New York City, so why on earth would there be a cow nearby? It was 2001, and only a few people were present in class that day. Just a few other students and the teacher.
Once the teacher is screaming in pain, the students see their chance, and make their getaway out the door, and spend the rest of their day at home in peace.
