Well, after the divorce, I went home and turned all the lights on!

The line plays as a characteristically Larry David-style punchline: a mundane, slightly petty act (turning on every light) becomes a symbolic declaration of freedom after a divorce. It suggests a release from domestic negotiation—no more shared rules about waste, thrift, or “how things are done” in a household. The humor comes from the disproportion between the life event (divorce) and the trivial “celebration,” implying that independence is felt most sharply in everyday habits. It also hints at loneliness or emptiness: the house is lit up, but the gesture is more compulsive than joyous, underscoring the awkward, self-justifying ways people cope with major transitions.
