" I finally understood why laughter is a mark of wanderers, from the holy fools of Old Russia to the roadies of rock music. It’s the surprise, the unexpected, the out of control. It turns out that laughter is the only free emotion—the only one that can’t be compelled. We can be made to fear. We can even be made to believe we’re in love because, if we’re kept dependent and isolated for long enough, we bond in order to survive. But laughter explodes like an aha! It comes when the punch line changes everything that has gone before, when two opposites collide and make a third, when we suddenly see a new reality. "
