Star Wars "Pants" Lines
This probably takes some explaining. I recently received an e-mail containing several Star Wars quotes that sounded funny when a key word was replaced with "pants". I do not know who first came up with the idea or who originated the forward. When I got the e-mail, I spent a good hour thinking up additional quotes. It proved to be a fun and rewarding experience. It was, in fact, the best way of putting off term papers I have seen to date. What follows is the fruit of my--and many other people's--labour.
Some of my favs-
I find your lack of pants disturbing. --Darth Vader, SW
You are unwise to lower your pants. --Darth Vader, RJ
Great, Chewie, great. Always thinking with your pants. --Han, RJ
I recognized your foul pants when I was brought on board. --Leia, SW
A tremor in the pants. The last time I felt it was in the presence of my old master. --Darth Vader, SW.
Hey, don't worry. Chewie and me got into a lot of pants more heavily guarded than this. --Han, RJ
Jabba doesn't have time for smugglers who drop their pants at the first sign of an Imperial cruiser. --Greedo, SW
How long have you had these pants? About three or four seasons. They're up for sale if you want them. --Stormtrooper, Luke, and Ben, SW
I want them alive. No pants. --Darth Vader, ESB.
Knowing my luck, you've probably all seen these b4, but i hope some are new to you
