there are usually more than two options in any given situation. and the correct answer to many questions may be a blend of the multiple (not just two) options available. the modern mind seems satisfied with this black and white, all or nothing approach, and with the limits imposed upon options for thought and actions. witness the president's dictum that you are with him or with the terrorists, implying only two options and no grey areas.

perhaps the answer to this question incorporates both those options, and perhaps the option that hey, it's just fun. and maybe there's a mix of all three, or two, or no mix at all depending who you ask.

personally, i suck at tricks, but i try them for one reason only. they're fun.
