C'mon you hippies! Don't tell me you still didn't laugh... >:)

And to add to that idea, maybe you could have a coin slot in Palpy's chair that he has to feed before the DS laser will shoot. Someone could take James Karen's line from INVADERS FROM MARS (1986) and try to manipulate it so it sounds like Ian McDiarmid: "Great Scott! Doesn't anyone have a penny?!?"

Hell, everything on the DS2 could have a coin slot (you hear Vader having to scrounge for change and dropping a toll booth's worth before the shuttle door drops down; same thing when the elevator arrives in the Emperor's tower before the elevator door will open). Hey, Death Stars aren't cheap you know!
