Jack Me Some Lumber is one of the first daily quests you'll encounter upon arriving at the Argent Tournament. Neither of them have any impact on the tournament itself, so they can be skipped if you so choose. They only award gold, no reputation or items, so avoiding them won't hinder your progress through the Tournament content whatsoever. However, the gold is pretty good and the quests are quick, so if it's gold you want then it's gold you'll get.
What's going on in these quests, you ask? Well, the Argent Crusade has outsourced the construction of their coliseum to the Goblins. I don't think I need to elaborate on how catastrophically dumb that is, do I? If you want to help these Goblins strip Northrend of its many natural treasures, just talk to Bezzle Blastbolt and his brother Bozzle Blastbolt. The latter of the two offers A Chip Off the Ulduar Block which we will discuss another time.
So what do you need to do here? Accept the quest, fly out to the western portion of Crystalsong Forest, just north of the Violet Stand. You'll find yourself in amongst a load of trees, as you'll see in the picture at the top of this article. Ask yourself, "One of these things is not like the other things. One of these just doesn't belong! Can you guess which thing is not like the other things before we finish this song?"
