I've probably suggested this before, but when Lando announces the Empire has taken over and everyone should split, cut to random scenes of panic and/or looting. The evacuation scene in Spaceballs could work here.

And when this beloved character appears...

Someone off screen should yell "Ice Cream Man!"

Also, I found this when I picked up the latest MST3K volume today.

Carrie Fisher is in the fourth movie of the set.

I'll report back when I've actually watched it. :)
