There’s something from Field of Dreams that’d be funny for when Vader kills Palpatine, a bit where James Earl Jones says “Oh my God… You’re from the 60’s! Out! Back to the 60’s, back, there’s no place for you here in the future!” https://www.youtube.com/watch?v=oL_Wfc2yb90
When I watched that clip it struck me as funny if he just started yelling crazy, psychotic crap at Palpatine before suddenly throwing him over the railing.
(Also, his line “Who the Hell are you?” when he first opens the door in the clip is bound to be useful at some point.)
