All quotes come from Psychonauts.  You just can't beat that game!   

Doctor Loboto: Little boy, I am sorry to say that you have a very serious mental problem. The trouble originates in this area here. The area that we in the medical profession like to refer to as... the brain! You see, son... it's just no good! I hate to be so blunt, but... you have the insanity... of a manatee!
Dogen: I know. People are always saying that. What do you think's wrong with my brain, doctor?
Doctor Loboto: How should I know, I'm a dentist!

Raz: I work in the sewers.
Non-Sewer-working G-man: Gross! That is a terrible job! I would never let you date my daughter.

The Milkman: I am the Milkman. My milk is delicious.

Den Mother: I told you not to follow. Now YOU MUST DIE!
Razputin: But--
Den Mother: THAT IS THE WAY OF THE RAINBOW SQUIRTS!

Raz: [Refering to his gun] It's fake. I'm worried the other assassins will laugh at me.
"Assassin" G-Man: Shhh... Don't broadcast that fact, they look real.

Dr. Loboto: Well, I've reviewed your chart, little girl. The bad news is, we're going to have to remove your brain... strap it into an armored battle tank, and have it shoot down innocent civilians with its concentrated psychic death beam!
Lili: I'm gonna kill you so much.
Dr. Loboto: The good news is that your insurance should cover the whole thing.
