Dan and Kelly take on a topic that's been dogging graduate students for millenia (a word my mouth-breathing spellchecker doesn't recognize as the plural of "millenium"). Why does it have to be so fricken confusing? Is it all a big scam, or is there something to be gained from making the reader struggle to keep up? As usual, the boys have more questions than answers, but if you pay attention, you just might learn something anyway.
