If Tom is completely nuts, then his kids will be completely sane. Unless it's a chemical thing.

I know nutty people who have perfectly sane kids... in fact, the nuttiness of their parents drives them to utter sanity. Take note, future fathers... to have the best kids possible, be a
total jackass.
Placenta is definitely nutritious. The only reason we don't eat it is because of our cultural hang-ups. In many cultures, it's perfectly acceptable. For squeamish Westerners who think eating duck embryos is disgusting (go Fear Factor! I always laugh at that show... some of that stuff is served in
restaurants around here)... it isn't.
But then, I'm one to talk. After talking about eating sapient species (the old "Stop Whaling" petition thread), I had some nasty dreams about eating babies in a hot pot.
