Missed that episode of "How I Met Your Mother" with Katy Perry? Or when Liz Lemon fell for astronaut Carol (Matt Damon) on "30 Rock?" Thanks to the power of Netflix, you can now stream those entire series or just select episodes.



And (you may have heard) they've got their own original comedy series and they're pretty darn good: "Grace and Frankie," "Unbreakable Kimmy Schmidt," and "Arrested Development" also calls Netflix home now.



You can also check out lesser-known sitcoms like "Sirens," or catch up with classics like "M*A*S*H."



Of course, if you wait too long, these shows may no longer be available. As with all comedy, timing is everything.
