In addition to deep and profound philosophy, classical Athens also scores in a slightly more prosaic subject: the earliest documented mention of bedbugs comes from them. It's in a play called The Clouds, written by Aristophanes.
In it, no less than Socrates is instructing a young man named Strepsiades. Socrates asks his student what deep thoughts he is thinking. Strespiades replies, "Whether there'll be anything left of me after the bedbugs have finished chewing."
