There are so many things we love about How I Met Your Mother — but one of our favorite things about the show is that it totally changed our vocabulary forever. The beloved sitcom taught us not only a ton about dating and friendship, but also gave us invaluable life lessons — perhaps the best being that nothing (and we do mean nothing) good happens after 2 a.m.!

Plus, Ted, Robin, Barney, Lily, and Marshall gave us countless phrases and expressions that have entered our lexicon and — by the looks of it — won’t be leaving anytime soon! Think you know every single phrase that has entered our lives thanks to HIMYM? Test your knowledge by taking our quiz below!
