"She died laughing."
 * The description of Zero's dehydrated face in the book, especially when it's compared to a jack o'lantern.
 * Not to forget the drooping eyes and mouth bit. *shudders*
 * That moment in the movie where what might be Sam's ghost stares blankly at Stanley before fading away.
 * The Yellow Spotted Lizards,when Stanley finds a hole full of them.
 * The way Kate Barlow dies after being bitten by one of them, oh God, the way she dies.
