No famous lines from the highest grossing movie?

How can the highest grossing movie of all time (and by some accounts this makes it the best movies of all time) not have any memorable lines that have made their way into pop culture?

Some examples:

Star Wars: "Luke, I am your father", "use the force"
Forrest Gump: "Run, Forrest, run!""Life is like a box of chocolates"
Jaws "You're gonna need a bigger boat"
Terminator 2 "Hasta la vista baby", "I'll be back"
Captain Phillips "I'm the captain now"
Goodfellas "Funny how? Like a clown?"
A Christmas Story "You'll shoot your eye out kid"
Wizard of Oz "We aren't in Kansas anymore" "I'll get you.. and your little dog too!!"
Titanic "I'm the king of the world!!"
ET "ET phone home"
Scarface "Say hello to my little friend!"
Apocalypse Now "I love the Smell of napalm in the morning"
Big Lebowski ... let's not even get started.

etc etc etc

Avatar doesn't have any lines like this.

Where are the memorable characters? Memorable scenes even?

Darth Vader
Hannibal Lecter
The Godfather
The Wicked Witch
Forrest Gump
The Terminator
Alien
Freddy Kreuger
Snow White
Little Mermaid

Say any of those names and everyone will know who you are talking about. I have never heard anyone mention any Avatar characters by name. I have heard "the blue chick alien" and "the paralyzed dude" and that's about it. That tells you a lot right there.

What a strange movie this Avatar; giant box office earnings, little to no staying power in our daily lives. Just like the bag of popcorn you ate watching it, once it was done it was never thought of again.
