Whether people are setting up Trivial Pursuit at home or attending a pub trivia night, the basic premise remains the same: they're enjoying the thrill of providing correct answers to questions about lesser-known facts.

"You get a rush or a neuro-reward signal or a dopamine burst from winning," John Kounios, Ph.D., professor of psychology and director of the doctoral program in applied cognitive and brain sciences at Drexel University in Pennsylvania, told Healthline. "I think whenever you’re challenged with a trivia question and you happen to know it, you get a rush. It's sort of like gambling."

Only it doesn't really have any downsides.

To prepare you for these battles (or at least to make your Friday more interesting), Bored Panda snuck inside the 'Today I Learned' (TIL) subreddit and hand-picked some of the most interesting tidbits of information that people have shared there.

Oh, and if you want more, fire up our earlier TIL lists here, here, and here.
