Oedipus and Jocasta from 'Oedipus Rex'
Think of the worst couple you know. It might be those two people who are always making out by your locker, or maybe it’s your friend and her boyfriend who share a Facebook account, or maybe it’s Kim and Kanye. All of them are bad, but none of them are “dude killed his father and married his mother” bad.
Now, to be fair, neither Oedipus nor Jocasta knew about this before they got hitched. Like the rest of us, Jocasta was a single woman bound to marry whoever could answer the riddle of the Sphinx. Unfortunately, the man in question was her long-lost son who had unknowingly just skewered his own father. Yikes.
But to add even more confusion to the situation, Oedipus and Jocasta have children. Are they his kids or his siblings? Who's to say?
