Alexander's momma had stink-ass breath

"There was also dispute about [Alexander the Great's] parents. Much of this was posthumous legend; the Persians later fitted Alexander into their own line of kings by a story that Olympias had visited the Persian court, where the king made love to her and then sent her back to Macedonia because her breath smelt appallingly bad."
--from Robin Lane Fox's Alexander the Great (1973)

Note: In the upcoming Oliver Stone movie, Angelina Jolie plays Olympias, Alexander's mother. No word as yet on how Jolie's breath smelled.
