T-Rex: One day Cassandra got caught up in some baloney, and ended up being cursed by the god Apollo!
T-Rex: Mondays, am I right?
T-Rex: Anyway, Cassandra could now see the future, but nobody would EVER believe her prophecies!
T-Rex: Cassandra was like, okay, sweet, I can work with this. She bet on sports matches and made a LOT of money, since bookies LOVE taking the money of someone who's making a bet - a PROPHECY, if you will - on who will win, especially if the bookies INSTANTLY and FERVENTLY believe she's incorrect. Before long she was loaded, but had also attracted a lot of attention from some VERY unsavoury characters.
Utahraptor: They wanted to kill her and take their money back?
T-Rex: Exactly!
T-Rex: But Cassandra was now INVINCIBLE. If she foresaw her death, all she had to do was tell her murderers that they'd succeed in killing her. They'd instantly believe they'd fail and so abandon the attempt. Apollo was like, "man, this wasn't what I intended at all. Frig, guys. She's owning me down there."
T-Rex: However after she spoke with him he was convinced taking back his curse was pointless, and Cassandra's rule was characterized by peace, prosperity, and daily global broadcasts that nobody EVER believed would come true -- but damn it, she got results!
T-Rex: THE END.
