Well, I think there are some characters that say some pretty funny lines!
Tyber Zann ( to Jabba the Hutt
" If you don't keep to your promise, I will personally come to Tatooine and feed you to your own Rancor. "
The voice in which he says that line is part of what makes it funny.
There are loads of funny lines just like these, mostly said by Tyber himself.
Anyobody else think so?
