Some drink to forget, others drink to remember the president of Turkmenistan, the rate of rising sea levels, or methods of HIV transmission. These are just a few of the edifying topics covered at pub trivia nights around town that also benefit local nonprofits.

“Is this your first time?” asks Rachel Monfils, with a smirk, to a 20-something couple registering for sex trivia night at North Portland’s Florida Room. Monfils works for Planned Parenthood Columbia Willamette, the host and beneficiary of this monthly event. Someone from the drink line leans over: “It’s always awkward the first time, but it gets better!” Double entendres dominate team names (“Britney Queers,” “Pabst Smears”), and the trivia itself ranges from pop culture to current events to sex education.

More subdued is the monthly climate change night at Oregon Public House, hosted by geologist Owen Rudloff and benefiting scientific nonprofits. Rudloff isn’t messing around: In October, participants had to know the nitty-gritty of a recent climate report and the definition of “moraine.” (The eroded sediment at the edge of a glacier. Obvi.)

And nonprofit World Oregon (formerly the World Affairs Council) hosts a quarterly international trivia night for young professionals—though anyone is welcome—at Migration Brewing Company. Because who doesn’t want to try to remember the capital of Belarus for fun?
