I had this particular episode of Duck Dodgers up before, but it was taken down when the poster on YouTube lost his membership due to copyright issues. Now, it's back.
In "The Green Loontern", Duck gets a Green Lantern uniform by mistake due to the stereotypical dry cleaner mix-up, a trope that goes back years. Filmmaker Kevin Smith makes a brief appearance as Hal Jordan.
D'ya really want any more reason for DC & WB to do another crossover?
