...about a philosopher who'd had a turtle dropped on his head?
I was definitely talking with someone (JesSe? Josh?) about that -- he/she/it was saying that other schools of philosophy were discrediting the deceased diatribist (har har har) by saying, "Well, how smart can he be if he died when a turtle fell on his head?!"
Turns out he's actually a Greek playwright -- the unfortunate dead, not the person talking to me.
Aeschylus:
A Greek playwright back in 500 BC. Many historians consider him the father of Greek tragedies.
How he died: An eagle dropped a tortoise on his head.
According to legend, eagles picked up tortoises and attempt to crack them open by dropping them on rocks. An eagle mistook Aeschylus' head for a rock (he was bald) and dropped it on him instead.
