The game that Marge and Bart play in this episode is called "Earthland Realms" and it is a parody of the hit MMORPG "World of Warcraft".
Couch: Repeat of the couch gag from "Simpsons Christmas Stories" where The Springfield Shopper reports, "COUCH GAG THRILLS NATION".
Bart: Mom, I'm going to give you life the way I imagined you gave me life--by pressing Alt-F5 repeatedly! (His game character places a zapping gaze into her eyes as she's brought back to life, then he groans and drops to the floor)
Marge: Bart, you brought me back to life… (Sees her character now exhibits the lower part of a pig) …as best you could.
Nelson: HA-HAAH!!! (His character is a human head with pigeon wings who flies overhead, makes fun of her, then bumps into a wall and drops into a torch, getting incinerated in the process.)
(After Bart brought Marge's character back to life)
Marge: Wait till I tell the other moms you gave two-thirds of your life force to save me. What a good boy.
(An angry mob busts in)
Moe: He's weak!
Comic Book Guy: Slay him and take his experience points!
Bart: Wait, stop. If you kill me, I'll egg your houses in real life!
Mrs. Krabapel: It's still worth it!
(She stabs Bart in the eye)
Bart: Jumpin' Johnnycakes! Those dames are cheesed!
Homer: Son, I'll never understand women if I live to be 40.
Bart: Big if!
Homer: You said it! Enjoy me while I last. (Both laugh)
Bart: Want to go slam a few beers?
Homer: Want to watch me?
Bart: You know it! (Both leave for Moe's.)
Mrs. Krabapel: This game is a great way to meet eligible men who can afford a computer.
(Skinner's character, a scaly turkey, comes up)
Skinner: Or have access to one in the school library.
Mrs. Krabapel: It's amazing how you can be a turkey in every reality.
Skinner: What's important is we're talking.
