The infamous "Fighting the Frizzies at eleven" comment by the news anchor. This guy's been given an absolutely absurd sentence to read in front of millions of people, and he says it with absolute conviction.
Fitting being during a show with fuzzy-wuzzy Wookies. Maybe they'e the mythical Frizzies!
The sheer fact that Darth Vader appears in the special (in stock footage with his only line of dialogue redubbed).
A more straight example: Deadpan Snarker all-business bartender/owner Ackmena can jab as only Bea Arthur can.
Ackmena:(to customer) Well, I'm certainly not going to get rich with customers like you. I thought I taught you to drink faster than that. Well, at least you're steady.
Ackmena:(to Krelman) We are talking. You're not ordering. I'm not pouring. We are not drinking. We are talking.
As Jack Packard in Best of the Worst pointed out, if you look hard enough, you can see the exact moment at which Harrison Ford stopped caring even the slightest bit about being in it.
Harrison Ford's hilariously uncomfortable reaction when Conan O'Brien surprised him with a clip of Han's tender moment with Chewie's family. One gets the impression that the studio audience's presence was the only thing stopping Ford from murdering him for that.
