Liked the "Crow-bi wan Kenobi" line...very clever.
The only thing to watch out for is the length of the jokes. Nobody's going to fault you for running over movie dialogue (heck, I do it), but make sure it doesn't happen too often. You might end up overrunning some dialogue that might set up your next joke (again, guilty), or leave the joke on too long when it works just as well with a bit more brevity. Case in point, the "New Jersey" joke. I think that joke works great in that spot, but it goes on for just a little longer than it should, since it begins running into too much stuff and the second half of it is self-explanatory. My family is from Jersey, I've heard all the jokes before, so leaving at just, "And that includes New Jersey, too!" may give it better flow.
I got this on Blu-ray and haven't gotten a chance to watch it yet. Maybe once you've gotten it done, I'll give it a look.
