This month, show Pioneer Square who’s the geekiest of them all.

Is your intelligence heightened after a good buzz? Do you have a keen (and rather embarrassing) knowledge of obscure information? Well, Geeks Who Drink (GWD) and Merchants Café and Saloon invite you to prove it at Pioneer Square’s Holiday Trivia Nights, which will be held from 6 to 8 p.m. on both Thursday, Dec. 22, and Thursday, Dec. 29.
