EASTER EGGS

1. On Disc 3, go to the Extras menu for Deep Space Homer. Highlight the "Play with commentary" and then press Right. An icon will appear on the right - a picture of Bart's ear (see left). Press Enter and you can listen to audio outtakes from James Taylor.

2. On Disc 4, go to the main Extras menu (press Left then Enter). Select "Art & Animation". Selecting "Animatic with commentary" plays part of the animatic for Sweet Seymour Skinner's Baadasssss Song, with commentary by Matt Groening, David Silverman, Bob Anderson, Mike Anderson and Lance Kramer. However, if you highlight the "Animatic" option on the menu instead, then press Left you will highlight the 100th Episode ribbon. Press Enter to play the animatic with a different commentary: this time by Matt Groening, David Silverman, Bob Anderson, Mike Anderson, Lance Kramer, Lance Wilder, Paul Weed and Wes Archer. This is also accessible using the audio button.

There are semi-secret animations in each of the main menus: if you highlight the "EXTRAS" option and press Up, you will highlight an object in the room (Left or Right will highlight a second object if there is one). Pressing Enter plays another animation or sound. Disc 1: You can highlight the gramophone and the lever on the right: the gramophone plays some music, while the lever activates an alarm. Disc 2: You can select the television to play the Itchy & Scratchy opening credits, or the casino sign to make it flash. Disc 3: Highlighting the Lisa Lionheart doll on the counter and pressing Enter makes it play one of two Malibu Stacey phrases for some reason. The phrase are: "My name is Stacey, but you can call me [wolf whistle]" and "Thinking too much gives you wrinkles". Disc 4: Selecting the geode on Mrs. Krabappel's desk makes it sparkle; Selecting the Marge plant makes it frown and murmur. ANIMATIONS Each DVD has a different main menu: a scene containing items from the episodes on that particular disc. There are a total of six animations for each menu, in three pairs: a random one of the three will play each time you start the menu. The episode menus themselves use original couch gags, like they did for the Season 3 DVD.   Special Features menu On each disc there is a "Special Features" menu which houses some animation features; This can be reached by selecting the large button to the left of the screen on the main menu. The menu features Burn's train from the episode Burns' Heir, with Bart watching over it. Several characters come past on the train (the animations are in groups of two passes). 1. Itchy & Scratchy ride past on the train. The second time they come through, Itchy throws Scratchy onto the track, runs over him, and drags him behind the train. 2. Maggie passes on the train, waving a hat. Then Smithers passes, doing the same. I'm not entirely sure what the connection is here. 3. Homer rides the train carrying a glowing carbon rod; when he passes again there is no rod, but Homer is glowing all over. 4. Snake is on the front of the train, and Wiggum on the back, trying to catch him. When the train returns, Snake has tied Wiggum up. 5. Milhouse passes. The second time, he is covered in snow: this was referred to in Burns' Heir. 6. Captain McCallister comes past and says "Arr". When he passes again, he is fighting the squid (from Homer's Barbershop Quartet).   Language Selection menu This menu features Bart spray painting various things on the school wall. A digruntled Groundskeeper Willy comes by after and washes it off. The phrases Bart spray paints are in several different laguages.   DISC 1: Homer's workstation 1. Mr. Burns, as a vampire, comes in and bites his neck, but doesn't like the taste and spits his blood out. The three other Be Sharps enter and sing which makes Mr. Burns melt. 2. Sir Oinks-A-Lot (Springfield A&M's mascot) runs in; the nerds follow and try to catch him - they miss but they manage to chase him out. 3. The gremlin enters and starts taking bits out of Homer's workstation; Bart runs in and tries to wake Homer - we see that Sideshow Bob is after him. 4. Flanders as the devil tries to feed half a donut to Homer, but the future vision of Mr. Burns (with his head in a jar) and Smithers (as a robotic dog) enter and scare him off. 5. A bunch of monkeys enter and roam around the office, then run off. This is the only one which isn't from an actual episode. 6. Homer falls off his stool - somehow this manages to wake him up, even though he's slept through everything else. He gets back on his stool and falls asleep again. DISC 2: Bart's room 1. Homer appears at the window, guided by Colonel Klink. Mindy in the clam, held by Lenny and Carl as cherubs also appears. Homer screams and falls. Burns' monkeys fly past after. 2. Marge and Ruth fly past the window in the car, followed by Chief Wiggum, eating a donut. 3. The walking house from Homer The Vigilante walks past, after which Molloy reaches in for the TV. Bart frowns at him and he disappears. 4. A plane flies past the window with a banner saying "Visit Burns Casino". 5. Several characters appear at the window as if on the trampoline: Lisa, Otto, Wndell and Brad Goodman. 6. A tidal wave washes past the window, with Flanders and Todd in a boat floating past. Then Captain McCallister comes past, fighting a squid. DISC 3: The Kwik-E-Mart 1. Homer in space gear floats in, tied to a rope. He leaves with a bag of potato chips. 2. Stampy the elephant comes thought the door with Bart in his mouth. Apu give him a bag of peanuts and he leaves. 3. Homer enters, wearing the oversize novelty hat. He staggers about and buys some expired ham then leaves. 4. Nelson, Jimbo and Kearney enter and steal as much as they can carry. 5. A wave enters the store, and the Flanders-es-es ride in on their boat, buy something, and ride out. 6. Apu pulls the string on the Lisa Lionheart doll, and it giggles like the Malibu Stacey doll did. DISC 4: Mrs. Krabappel's classroom 1. Sideshow Mel tries to get the monkeys to play, but they don't play much at all. 2. The Simpson family enter...but wait, it's not them: it's the actors who played them in Burns' Heir, including Hans Moleman. 3. Superintendent Chalmers enters and Santa's Little Helper comes out of the vent, knocking him to the floor. Then Willie comes out and lands on him. 4. Lenny enters with tobacco and a metal pot; He spits in the pot and takes a bow. 5. Bart pokes his head up from behind Mrs. Krabappel's desk. Skinner enters and points at him. Then the French waiter staggers in, covered in mouse traps. They all run off. 6. Mr. Burns and Mrs. Bouvier come in and dance.
