I know the Lewinsky thing is the most horrible thing a sitting US President has ever done (*cough*), but I love the fact that the leader of the free world, the most powerful person in the world, slept on the couch for months after he told Hillary about the affair. From Slate's Condensed Bill Clinton:
Meanwhile, I was still sleeping on a couch, this one in the small living room that adjoined our bedroom. I slept on that old couch for two months or more. I got a lot of reading, thinking, and work done, and the couch was pretty comfortable, but I hoped I wouldn't be on it forever.
Doesn't matter if you're a prince or a pauper, if you're unfaithful to your partner, you're sleeping on the couch.
