Ok this thread came from the Philadelphia Flyers message board.
Basically you pick a topic, and you have to start the sentence or word with the next letter of the alphabet. (person who does the letter with Z starts a new topic in which it restarts to A)
Say the topic is Beer...
Next could be
Bud Light... So on.
Ok we are At C, if this thread grows like the other one, then i would be happy lol.
