To understand why "Airhead" ate his school money answer key, I would need more context about who Airhead is and the specific circumstances surrounding this incident. However, if we assume Airhead is a fictional character, it is likely that he ate the answer key to avoid getting caught cheating or because he didn't want anyone to see the correct answers. This fictional scenario suggests that Airhead may not have been prepared for the test and resorted to desperate measures to hide his lack of knowledge.
