They gave me a free history lesson, and I love them for this

Now, let me explain what I meant. 🤣
As it turned out, today we had a history test. The topic was Ancient Greece. I was astonished, but this was not the only issue... My friends said the test will include Alexander the Great and Hellenstic Greece; these were the topics which we never took in classes (also, our teacher didn't even say anything about them).
I didn't panic: I googled the lyrics of Iron Maiden's song "Alexander the Great" and, while reading, was checking every piece of information. And you know, this actually helped me. 🤣
Thanks for attention. 🤣
