yes, little drummer boy yay. I liked last years christmas special better, but oh well I'll take what I can get.
To answer the easter question, Der Schriftsteller eluded to whats going on, but Ill try to spell it out. Way back in the day, some cultures celebrated Easter (original spelling and pronunciation ?) as the spring festival of fertility. It is even mentioned in Acts 12:4 (KJV). Rabbits and chickens tend to be symbols of such. It turns out that our the ressurection of Christ, Passover, and the original easter are closely timed, and so were brought together at some point.
So, in short, while Christians celebrated Easter as the resurrection of Jesus, other cultures celebrate fertility bringing in the eggs and bunnies.
