Well, yes, beer does go bad, but exactly when depends on your definition of bad (and possibly how many you've already had!). So, does beer expire... when properly stored, the shelf life of beer past its best before date is approximately: Although all food and drink lasts for a shorter period of time if they are not stored properly, proper storage extends the shelf life of beer beyond its best by date.
If disturbed by a blockhead attacking or approaching too close, the troll will pursue the interloper. It is almost as capable of climbing (including ladders), jumping, swimming, and otherwise navigating a cave as any blockhead, although it moves slower, allowing most blockheads to escape.
Then they burned the old troll and her to ashes, and explored the cave, where they found plenty of gold and treasures. They went up above the cave, and found a window in it, through which they looked, and saw four trolls lying asleep beside the fire, over which a large porridge-pot was hanging.
