If you use pyrokinesis on the birds in the main campground, they burst into flames and leave behind a roast chicken which Raz can eat to regain health.
Not to mention roast squirrel.
Even more pyrokinetic fun: if you use it on Sasha Nein, he'll deadpan "I'm sure you can find a more productive use for that skill, Razputin".
Try using it on the giant tree timeline in the camp parking lot. Raz will groan "Aw, they don't trust us with anything!". The devs of the game fully expected people to try and burn everything they could, including the very large piece of wood (the timeline) in the parking lot.
Wait a minute, I think there might not be a conspiracy after all! It's possible I'm just suffering paranoid delusions linked to an entity I call The Milkman, who is in actuality... (grenade wears off)the mummified remains of Abraham Lincoln!
Here's one of the best ones from the G-men:
"Okay, I have to think...do this watering can and I have a history?Ē
"Oh my god, why am I holding a gun?"
"I hope I haven't killed again."
Sasha, before giving you a target to practice with, describes the most horrendous thing imaginable and out pops... an enamel-glass lamp. Also, his wonderful "And the world is a better place." after PSI blasting said lamp out of existence. And his disgusted noises at the new lamps appearing. Well, let's just say the entire scene up to when the Censor Machine flips to overdrive.
Sasha: Excellent. A victory for good taste.
After shutting off all the Censor valves, Raz and Sasha have the following exchange:
Near the end, when the asylum becomes extra-flammable due to an entirely ridiculous series of events:
Edgar: OH, NO, I SPILLED ALL MY TURPENTINE AND ACETONE!
If you "use" the cake meant for Pokeylope on Lili before you put it beside his cage, you will get this beautiful gem.
Raz: Hey, if I shoved this cake in your face right now, you wouldn't be able to do anything as revenge!
Lili: Not right away, no. But a revenge that painful would take lots of planning, anyway.
When you first get the Confusion Grenades, try using one on the poster dog. The resulting cutscene is absolutely hilarious.
"No, wait! God...is cat...spelled backwards."
This little bit, which you can find after Basic Braining, after Mikhael asks Raz if Lili is his girlfriend:
Mikhael: Is okay. Girls only good for one thing, anyway. Wrestling.
After Basic Braining, go to the lake and talk with Elton Fir, who will explain that he can telekinetically talk to fish. Hang around long enough, and they'll stop talking to him about Linda and start teasing him about wanting to "spawn" with Lili. He gets annoyed and says humans don't technically do that.
The real Augustus' line after blasting mental Augustus into the meat grinder:
"I have a lot more hair than that!"
When you're learning telekinesis, Cruller is remarkably patient if you pick him up.
Sasha: This confirms my suspicions: We're trapped in the hideous fantasy of a hardcore mainstream gamer! We'll defeat them with science, using these magic guns I invented.
Scott Campbell's official comics for the game were lost during a site redesign, but can still be found online elsewhere. As also seen in the Vault Viewer commentary folder below, he's quite funny in his own right.
Coach Oleander: Corn tastes better in the outdoors, you guys think? Yes, especially during a battle when you're in a foxhole with the shells ripping the ground apart around you.
Sasha Nein: Corn is corn. The molecular structure does not change when exposed to fresh air.
Coach Oleander: I am about to challenge you to a psychic duel, Nein. How does that sound?
"PARTIES are so awesome."
Milla Vodello: [standing outside with eyes closed, humming]
Ranger Cruller: Miss Vodello, you havin one o' them mind parties?
Milla Vodello: Yes, darling. I'm preparing the classroom for the children.
Ranger Cruller: Kids love pin-the-tail-on-the-donkey.
Milla Vodello: Yeah, we won't be playing that game I don't think.
Ranger Cruller: Then the kids will miss out on a valuable lesson.
Milla Vodello: What lesson?
Ranger Cruller: Pinning. Also donkeys.
Admiral Cruller: [standing on the dock, staring blankly out at the lake]
Sasha Nein: Admiral? Stealing a moment next to the lake, eh? Before the kids arrive? Yes. Lake Oblongata is quite beautiful. But do not worry. Even with children bombarding its shores, it shall still be our lake.
Admiral Cruller [still standing in the same position]: Zzzzzzz
Sasha Nein: Ah yes, I see. Sorry for disturbing you. [levitates away]
Vault Viewer Commentary
Though technically not part of the game, the commentary that was released alongside the Vault Viewer in September 2011 was full of CMoF. It might not explain a lot about Psychonauts in and of itself, but in a way, it tells us about the mindbehind Psychonauts. Which explains almost everything in the gamenote The commentators are Tim Schafer and Scott Campbell, who was responsible for the artwork inside the vaults.
In the intro of the commentary:
Tim: Well, [Psychonauts] was made from 2000... zero. To 2005.
For example, "Oleander's Pride":
Scott: That's a flag for...country.
Tim: It's a flag for Country! [laughs] Cause we never said where this game is set.
Scott: That child is... he's in need to that box of crosses. Or math.
