'cause the show was created in the '60s and they had natal back then. Crazy if you think about it (with them being cavepeople and all) but maybe they had an earlier form of Christianity, lol.

but natal is jesus's birthday? .... he wasn't even close to being born around the stone age though (witch is the time period that the show takes place) and its just something that is funny to me haha
