Funny / Halo 3

  • The intro to the game is a monologue from Cortana (while we watch a shooting star descend from the night sky) explaining why she decided to work with the Chief rather than one of the many other Spartans. They're all very strong, very determined, very well trained. What does Master Chief have that they don't? He's lucky. Cue the falling star being revealed to be the Chief, in flames, falling form orbit and crashing to the Earth with all of the grace of a large brick.

  • The "password" Easter Egg starring various characters from Red vs. Blue:
    • Easy / Normal:
      Tucker: Hey, open up!
      Doc: Password, please.
      Tucker: You gotta be kidding me! What password?
      Doc: The password so we don't open the door for Brutes.
      Tucker: Do I sound like a Brute to you?!
      Doc: Well, you could be held prisoner by Brutes.
      Tucker: If I was held prisoner by Brutes and knew the password, then the Brutes could just force me to tell you the password and you'd open the door for them.
      Doc: ...Okay, well now I'm definitely not gonna open the door.
      Tucker: But we need ammo!
      Doc: Well why don't you go ask your Brute buddies, then?
    • Heroic:
      Simmons: Hey, open up!
      Grif: Password.
      Simmons: What?
      Grif: Need the password!
      Simmons: You gotta be kidding me! What password?
      Grif: Password! They gave it out at the staff meeting fifteen minutes ago!
      Simmons: Meeting? What meeting?! I was out here!
      Grif: Not supposed to let anyone in without it.
      Simmons: If the staff meeting just ended, no one outside is gonna know the freakin' password! Now open up! We need ammo and the Chief is out here!
      Grif: ...Does he know the password?
    • Legendary:
      Church: Hey! Open up!
      Caboose: What's the password?
      Church: Password? Oh man, I forgot.
      Caboose: Forgot... what?
      Church: I forgot the password.
      Church: No. I mean, I forgot the password.
      Caboose: No, okay, see, you - you got it wrong again. See, you said the same thing as last time.
      Church: (sigh) I'm being serious; I don't know the password!
      Caboose:: No no, see, you changed the first part. See, that - that part was the right part. See, now you've got the whole thing wrong!
      Church: No! I forgot what the password is and I just need you to open the door!
      Caboose: ...Alright, c'mon, man, now you're just guessing!

  • There is a saying: "Spartans never die, they're just missing in action." John-117 ends up actually MIA at the end.
