As is my custom, I

As is my custom, I have the Christmas tree lights hooked up to The clapper. (you know "Clap On! Clap Off!"). Jennifer hates it because it's not quite deterministic.

Plus Homer manages to turn it on or off with his bark. Which, I think, is kinda neat. It would be cool if he figured out that that's what he's doing. On the other hand, maybe it would only lead to incesant barking, so I guess it's better if he's not aware of his power.
