This is the worst kind of GTKY (getting to know you) question. It isn't even disguised under the premise of creating a useful list (i.e. your favorite brand, your favorite drink, your favorite joke... which are bad enough). It goes against the very purpose of the site in that there is no useful "knowledge" to be gained from this kind of thing. It's a social chit-chat message.
