Move over Britteny
Britteny Spears has been dethroned as the Queen of Marriage Travesty. All hail Mary Kay Letourneau. Long live the Queen. 
In case you don't remember Mary Kay, she is the elementary school teacher who, at the age of 34, seduced a 12 year old student, was twice impregnated by said student and served 7.5 years in prison for second-degree child rape. And they say homosexuals are oversexed?
What does this have to do with the theoretical sanctity of marriage? Now that she's done serving time and the boy is now a man, they were recently married. Oh, yeah. That's a healthy relationship, but no one would dream of forbidding them to marry. Well, maybe the boy's mother tried, but he's an adult now, so she has no legal standing.
I sincerely hope it works out for them. I'm having a hard time seeing how.
