What do you think are the funniest lines in all six Star Wars movies? And what movie is it from?? And who said it to whom?
There are many to choose from. Some of my favorite ones are:

"Will someone get this walking carpet out of my way?" Leia said it to Chewie on the Death Star. ANH

"Laugh it up Fuzzball" Han said it to Chewie for laughing at him when Leia call him a Scruffy looking nerfurder. ESB

Let me know what your favorites are.
