If you have a child that is born from a 20-year-old frozen embryo, do you tell him? And if you do, do you just blurt it out one day (“Hey, John, it’s so cold outside. That reminds me…”)? Do you wait until just the right time (“John, before you take that job in Arizona, there’s something I have to tell you…”)? Or do you build up to it, dropping hints at various points in the child’s development? For instance, at his bar mitzvah, when they do the inevitable photo montage screening, you could slip in a shot of an ice cube. (No, I don’t know that the baby is Jewish. In fact, no one does, since the embryo was donated anonymously. He’s probably a Frozen Catholic. Or maybe a Thawed-Again Christian.) (more at laughs4dads.com)
