That moment of realization when you discover apple seeds contain amygdalin, which metabolizes into hydrogen cyanide. Sure, you'd need to crush and consume about 200 seeds to reach toxic levels, but that's just nature's little game of chemical roulette.

Your body contains roughly 8,000 becquerels of radioactivity anyway, so what's a little more from your fruit salad? The real danger is the paranoia.
