If you're building a nuclear reactor or a bomb sooner or later you're probably going to want some plutonium, the most fissile isotope of which has an atomic weight of 239 (and a half-life of about 24,000 years).
Nobody seriously expects the Carnival of the Vanities to last that many years, but it has gotten to number 239. I think. As of this morning at 7 Central, it hadn't been posted yet.
