I love these little chocolate eggs with surprisingly clever toys inside. My family was addicted to them for a while, too, when they were available at a local import shop near my parent's house. I'm not sure, but I think I first encountered them while living in Budapest, where we all started calling them Kinder Eggs and the name stuck, instead of their actual name "Kinder Surprise".
But now I'll never look at them the same way again after seeing this creepy commercial.
