You''ll never guess Crosby's costume. (VIDEO)

Halloween is upon us, and it is time once again to dress up in costumes and trick or treat for candy. While this was fun when you were a child, you may have grown out of this tradition already. But hey, everyone likes to reminisce about their past right? The NHL recently sat down with Sidney Crosby, T.J. Oshie, and a few other players, asking them to name their favourite childhood Halloween costume. There are plenty of NHLers who want to be ninjas apparently. Except for "Sid the Kid" that is. Bet you can't guess what his favourite costume was as a child.
