G.I. D'oh/References

Cultural references

 * The title is a reference to G.I. Joe. "Grunt" is United States military slang for an infantry soldier. 'Annoyed grunt' is the script notation for Homer's favorite exclamation, D'oh.
 * When the colonel has the recruits do push-ups while Homer eats donuts, it is referencing a scene in the movie Full Metal Jacket. The movie is again referenced when Homer wonders if the drill sergeant will ask him "what his major malfunction is".
 * The Army recruitment film shown at Springfield Elementary uses "Arise, Ye Russian People" from Prokofiev's soundtrack for Alexander Nevsky before switching to Led Zeppelin's "Communication Breakdown."
 * Milhouse asks about The Doodlebops, a popular children's show.
 * The music playing during the assault course is the song Toy Soldiers by Martika.
 * When the mini-helicopter blows up, "That's all Folks" appears in the enemy screen.
