Wow, everyone's come up with some pretty bad quotes. Some are so bad they're funny and others are so bad they're painful. Here are some more that I don't like. Some of these might be slightly off since I don't know Menace and Clones as well as the other 4.

Menace:

Palpatine: We shall follow your career with great interest

Anakin: They blow you up!

Qui-Gon:He can see things before they happen
(really? why didn't we get to see that)

Watto: Jedi mind tricks don't work on me. Only money!
(how convenient)

Queen Amidala: You muzdo something
(she's supposed to say you must do something but that's what it sounded like)

Clones:

Obiwan: Why do I get the feeling you're going to be the death of me?

Sith:

battle droid: You're welcome!
droid (to r2) Hey you!
(why do all the droids sound like the chipmunks in this movie?)

Palpatine: Once more the Sith will rule the galaxy!!! And.we.shall.have..........peace (evil smile)
(I dunno if it was the way he delivered it or whatever, but it came out so weird it was funny)

Bail: My wife and I can take the girl. We've always talked about adopting a baby girl. She will be loved.
(too convenient)

Bail: What's going on here?
Clone: There's been a rebellion. I'm sorry sir, it's time for you to leave.
Bail: And so it is.
