Here's an idea I just had for a cartoon (I thought of it originally for a tee-shirt design):
Emperor Palpatine, Darth Sidious, Darth Maul, and Darth Vader are hanging around in a Laundromat in their skivvies. Both Sidious and Vader are standing, both in boxers. Darth Maul is sitting on one of the machines and has little red hearts on his briefs. Palpatine [also boxers] would be sitting in the main focal point of the picture. Beside them are two full baskets of clothing, and one empty basket. The two full ones clearly contain whites in one and bright colors in the other. They all look - at best - bored... Darth Sidious is checking his watch, with one hand, Palpatine is 1/2-heartedly thumbing through a magazine on a rickety little table (possibly something like 'Cat Fancy').
The title underneath is: "Dark Load of the Sith"
