Leia: Why, you stuck up, half-witted, scruffy-looking nerf-herder!
Han Solo: Who’s scruffy-looking?
Ben (Obi-wan) Kenobi: Luke, don’t give into hate. That leads to the dark side.
[Luke can’t levitate his X-Wing out of the bog.]
Luke Skywalker: I can’t. It’s too big.
Yoda: Size matters not. Look at me. Judge me by my size, do you? Hmm? Hmm. And well you should not. For my ally is the Force, and a powerful ally it is. Life creates it, makes it grow. Its energy surrounds us and binds us. Luminous beings are we, not this crude matter. You must feel the Force around you; between you, me, the tree, the rock, everywhere. Yes, even between the land and the ship.
[Using the Force, Yoda effortlessly frees the X-Wing from the bog.]
Luke Skywalker: I don’t believe it.
Yoda: That is why you fail.
