You think you know “Friends”? But do your friends know “Friends”? Here’s a good way to find out. Ahead of this weekend’s quasi-reunion, thinktank trivia is hosting games inspired by the ‘90s classic at Allston’s Common Ground on Feb. 20 and Dorchester’s Blarney Stone on Feb 21.  

Guests are invited to bring their “Friends” memorabilia and dress as their favorite character — bonus points if you can commit to "The Rachel” — to amplify the fan experience. Prizes are CASH, which is absurd but awesome, though there’s a $5 buy-in for individuals, though it’s encouraged to play as a team. Ideally a six-member one dressed as Chandler, Joey, Monica, Phoebe, Rachel and Ross with matching umbrellas who can clap to The Rembrandts in perfect harmony. 

Need a refresher course? Netflix has all 10 seasons of "Friends" streaming (with some fan-noted edits) for your binge-watching pleasure.
