Another deleted scene from Return of the Jedi:
Emporer: "Prepare to witness the true power of this armed and fully operational space station!"
Vader: "Um, boss."
Emporer: "What is it now Ani? Can't you see I'm gloating!"
Vader: "Well, remember those lasers that we ordered from Walmart?"
Emporer: "Ahhh yes! Quite a bargain if I remember. $4.88 each, right. No place better to shop. I must remember to commend them."
Vader: "Well, um. They're on back order. Apparently the Ewok slave labor has been staging a rebellion on the Endor moon and..."
Emporer: " WHAT?! That's it, we're getting our parts from Lowe's next time."
Vader: "Um, it's the same company."
Emporer: "Huh? Sam's Club?"
Vader: "Yup."
Emporer: "What, are there any stores that we shop at not owned by Walmart?"
Vader: "No, they appear to be forming some type of evil corporate empire."
Emporer: "They will see the true power of the dark side of the force!"
