Jokes about nuclear meltdowns on Fox’s "The Simpsons" are reportedly being edited out of some episodes, while other episodes are being pulled from the lineup, in several countries in the wake of the real-world nuclear crisis in Japan, according to The Hollywood Reporter.

The article reports that Austria’s ORF network has pulled two episodes: "Marge Gets a Job," which features Marie Curie and Pierre Curie dying of radiation poisoning, and "On a Clear Day I Can’t See My Sister," which contains characters joking about nuclear accidents.

Broadcasters in other countries, including Germany and Switzerland, are also reportedly screening the series for nuclear content.

Al Jean, the executive producer of the show, tells EW.com’s Inside TV that he understands the concern. "We have 480 episodes, and if there are a few that they don’t want to air for a while in light of the terrible thing going on, I completely understand that,” he said. "We would never make light of what’s happening in Japan.”

In the U.S., “Simpsons” syndicator Twentieth Television has sent a list of episodes containing potentially sensitive nuclear references to stations that air the show, the EW.com piece reports.
