Imagine a world where skin is yellow, hands have four digits, and idiots helm nuclear power plants. If this world is more real than imaginary, you are ready to climb into The Treehouse of Horror, Geeks Who Drink’s third all-Simpsons quiz. Although it's named “Treehouse of Horror” (in honor of the The Simpsons annual Halloween episode), the quiz covers everything Simpsons and is not Treehouse of Horror-themed. Teams are limited to 6 players and there’s an admission fee of $5 per player. The winning team may not get donuts — mmm, donuts — but they will also take home a cash prize between $200 and $500 (depending on total number of players). $5 per player; 8pm Wed, Oct 17; Firehouse Pub & Grill, 5380 Walzem, (210) 946-9600, geekswhodrink.com/198.
