I thought of that old joke, y'know, this guy goes to a psychiatrist and says, "Doc, uh, my brother's crazy. He thinks he's a chicken." And, uh, the doctor says, "Well, why don't you turn him in?" And the guy says, "I would, but I need the eggs." Well, I guess that's pretty much how I feel about relationships. Y'know, they're totally irrational and crazy and absurd and, but, uh, I guess we keep going through it because, uh, most of us need the eggs.
