Funny story about my junior high science class:

My 8th grade science teacher taught both Life Science and Earth Science (different classes for different grades). The teacher had graded our Life Science tests — which we took by filling in our answers on the teacher's own self-made bubble sheets — and was handing them back to the class.

As he handed the tests back, he announced to one student (loud enough so everyone could hear) that, while this student had failed this Life Science test, had he been taking the EARTH Science test he would have gotten 100% . . . because his answers matched the Earth Science test key perfectly.

0% for cheating and for not being observant enough to do it correctly.
