"Woo! So long, Camp G- * CRASH* "
In the book, When the Mary Lou boat is found, Stanley imagines that Mary Lou was a beautiful woman, but we all know how wrong he was.
"Go on, run! There won't be no Yelnats the Fifth!"
"Well that's just TOO DAMN BAD!" Both the timing and the way the line is delivered makes the moment totally priceless.
"Once, there was a magical place where it never rained. The end."
- Squid's reaction: "I don't get it."

Mr. Pendanski: "D-I-G, what does that spell?"
Zero: *knocks Pendanski cold with shovel* "Dig!" *runs away*

During a montage in which Stanley becomes accepted by the rest of the campers in the movie, Armpits lifts up his armpits. Everyone runs away from the stink. Trust me, it's funnier than it sounds.
When Mr. Pendanski asks Stanley whose fault it is that Stanley is at Camp Green Lake (obviously intending An Aesop about personal responsibility) and Stanley responds confidently, "My no-good dirty rotten pig-stealing great-great-grandfather!"
An Embarrassing First Name reveal in the film.

Zig-Zag: "Say, I didn't know Marion was a man's name."
Mr. Sir: "It ain't."

This line:

The Warden: "Now do as I say." *walks out*
Mr. Pendanski: "What did she say?"
Mr. Sir: "Not much."
Mr. Pendanski: "Then what do we do?"
Mr. Sir: "You do as I say." *walks out*
Mr. Pendanski: "But you didn't say anything either!"

When Armpit tries to give the warden a knob he found and gets his weekly shower tokens taken away, who's more upset about this? His cabin mates.

Squid: Man, you sleepin' outside!

When Stanley arrives to the camp, he's not too happy to be assigned a cot that previously belonged to someone nicknamed "Barf Bag".
