When Luke meets Jabba, and gets the 'trap door treatment', instead of a guard going down with him, Jar-Jar goes down, and gets eaten by the Rancor. :D
LoL ^^
OR someone can realistically edit in Jar Jar's bones in the Rancor pit. Then when Luke grabs a bone to put into the Rancor's mouth - it'll be Jar Jars leg bone (formerly connected to his hip-bone).
Alas, his death will have TRUE meaning.
