Presenter (to palaeontologist):"So what would happen if you mated
the woolly mammoth with, say,an elephant?"
Expert: "Well in the same way that a horse and a donkey produce a
mule, we'd get a sort of half-mammoth.
Presenter: "So it'd be like some sort of hairy gorilla?"
Expert: "Er, well yes, but elephant shaped, and with tusks."

When I was in college, a colleague at WTBS (no, not the Turner
superstation, but the 14-watt campus radio station from which Turner later

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.
