						I started with the first word with words of the form ABCDCD.  I had curara as one of my 20 or so first words, but I couldn't find an English word of the format _ u c u _ _ _ as the last word so I abandoned it.
 I sent the challenge to a few buddies and one of them (a computer engineer) came up with this in his email response:
 
 "A Vigenere cipher.  (Where you have a multi-letter key -- in this
 case, two letters -- which repeats through the message, giving varying
 shifting amounts for each message letter.  I just happened to be reading about these a couple months ago; that's the only reason I know the name.)  I swear, one of my first thoughts was that it might be a Vigenere, except I thought maybe the bolded/regular letters were message/key or vice versa, but that didn't produce anything, so I sort of gave up.  I wasn't sure how clever it was trying to be...guess I overshot.
 
 I focused on the fourth (i.e. two-letter) word, figuring that one of
 them had to be a vowel, which drastically narrowed down my search space.
 
 After that, I just did a brute force search, using an online Vigenere
 cipher encoding/decoding tool to give me the result of each try.
 
 Just a few tries before I got it, I was trying key QX, which gave me:
 ciroro cwtc tits eh jicinre
 
 That made me laugh.  Then, a few tries later I hit key QL, and I figured that had to be it -- was the first one where every word was at least pronounceable.  Couple googles later, and I was sure."

 Paste the puzzle in the first box and the key is QL.  Bingo bango, sugar in the gas tank.
