Al states that the Bundy-curse works in the way that, once starting to accumulate good luck, it immediately builds up an equal amount of bad luck. The sheer stupidity of Al is his own downfall, because, instead of immediately admitting his good luck, and consequently being "showered" with a little bad luck, he builds up even more good luck, only to be "drained" with bad luck. That is karma working its magic on a stupid person - one could conclude.
