How about having Jar-Jar innocently walking in the snow of Hoth, and then he suddenly gets hit by the Probe Droid when it 'lands'?
...or... by the time ROTJ rolls around, Jar-Jar has joined the Empire, and somehow became a gunner, or something, and when the SSD slams into the DSII, Jar-Jar gets his eye poked out by the pointy tip of the ship...just before the explosion. lol.
