Are you going through a Key & Peelewithdrawal waiting for the show to return later this year? Or - worse - are you not on board the K&P train yet?

For the uninitiated, Key & Peele is the brainchild of former MADtv cast members Jordan Peele and Keegan-Michael Key. The sketch show premiered on Comedy Central in 2012 and is now in its fourth season. It won a Peabody Award in 2013 and has also been nominated for a Writers Guild Award and an NAACP Image Award.

Key and Peele reflect on their greatest hits

Here are seven essential Key & Peele sketches to tide you over - or get you started:

The Valets/Liam Neesons: What is probably the duo's most popular recurring sketch features two valets/action movie super-fans, who discuss their love of all things Liam Neeson-related - while mispronouncing his name the entire time. (They're also huge fans of "Bruce Willy" and "Racist-Ass Melly Gibbons.") In "What About 'Non-Stop,' Though?," Neeson himself makes a surprise performance.

LaShawn and Samuel: Key and Peele use the gay couple "LaShawn and Samuel" as political humor to convey their thoughts on gay marriage and equal rights for LGBT people.

Obama and His "Anger Translator" Luther: In this recurring skit, Peele plays President Obama and Key portrays Luther, the commander-in-chief's "anger translator," who infuses his calmly delivered opinions with a little bit of rage.

Wendell: Peele's character Wendell is a lonely, nerdy guy who goes to great lengths to convince people that he leads a perfectly normal life, surrounded by family and friends - including his "girlfriend" Claire and their 15-year-old son, "Stimpy."

Substitute Teacher: Key and Peele are prepping a feature film based on Key's character Mr. Garvey, a substitute teacher who's so accustomed to working in inner-city schools that he has difficulty pronouncing his students' run-of-the-mill names correctly.

I Said Bitch: Come for the surface-level comedic setup (two men sneaking off to bad-mouth their wives), stay for the nuanced references to masculinity and gender roles in modern relationships.

East/West College Bowl: A staple of Key and Peele's annual Super Bowl special, this segment highlights some of the more unusual names among aspiring professional athletes.
