Native 1: "Was that person really trying to dress like one of us? We don't even dress like that! We never did!"
Native 2: "Calm down redman! It's Indian Halloween!"

Non-indian religious event occuring annually on December 25th. A day when people dress up like idiots and knock on your door expecting free food and gifts.
