Where would we be without the Simpsons, America's favorite nuclear family? In a world without Bart's furious chalkboard scribblings. A world without couch gags. A world without Squishees and Duff beer and "D'oh!" Sunday marks the Season 23 debut of The Simpsons -- a season that will include the 500th episode of America’s longest-running animated program. To mark this milestone, we asked Wired.com staffers to name their all-time favorite episodes, lines, nerdy send-ups and moments from the show. The picks kept rolling in, but we narrowed them down to 10. Enjoy them all, in chronological order, in the video gallery above. The Simpsons airs Sundays at 8 p.m./7 p.m. Central on Fox.

'Marge vs. the Monorail' Season 4, Episode 12 This parody song has basically erased the actual Flintstones song in my head. —Chris Kohler Without fail it's the Monorail episode, specifically the send-up of "The Music Man" (below) that is "The Monorail Song." —Josh Strom <script src="http://admin.brightcove.com/js/BrightcoveExperiences.js" type="text/javascript"></script><object class="BrightcoveExperience" id="myExperience1161759758001"> <param name="bgcolor" value="#FFFFFF"></param> <param name="width" value="660"></param> <param name="height" value="423"></param> <param name="playerID" value="3698508001"></param> <param name="publisherID" value="1564549380"></param>

'Deep Space Homer' Season 5, Episode 15 It apes 2001: A Space Odyssey, the greatest space movie of all time, then follows that up with one of the most-quoted Simpsons moments, the Overlord meme, when Kent Brockman says, "I, for one, welcome our new insect overlords." —Michael Calore

'Lisa’s Rival' Season 6, Episode 2 This was one of the funniest episodes for a Star Wars nerd. Instant classic. Also, Principal Skinner’s fascination with the toys was perfect. —Simon Lutrin

'Lisa the Vegetarian' Season 7, Episode 5 One of my favorite episodes of all time is when Lisa becomes a vegetarian. There are just so many classic parts: The "You Don't Win Friends With Salad" song, the flying pig, the hot dog contents thought bubble. And if that weren’t enough, cameos by Paul and Linda McCartney. I'm a vegetarian, and the exaggerated portrayal of both sides is pretty accurate. —Keith Axline

'Bart After Dark' Season 8, Episode 5 The musical revue in which, among other spectacular production numbers, the town's hookers sing, "We put the spring in Springfield." A great send-up of and homage to Busby Berkeley films of the 1930s. —Randy Alfred

'The Mysterious Voyage of Homer' Season 8, Episode 9 The idea of Homer on a spiritual quest, a la Carlos Castaneda, is hilarious. His "spirit guide" is a coyote version of Johnny Cash. Coyote: "There’s a lesson you must learn."

Homer: "If it’s about laying off the insanity peppers, I’m way ahead of you." Trippy fun. —Annaliza Savage

'Bart Carny' Season 9, Episode 12 I still use "It's the Carny Code" in conversation. —Angela Watercutter

'MoneyBART' Season 22, Episode 3 Spiked with graffiti jokes, this wild extended version of The Simpsons couch gag spirals out of control in the hands of street artist Banksy, who turns the intro into a subversive statement about overseas animation sweatshops. —Lewis Wallace
