On Futurama last night (it was the episode where the kids make a newspaper business to compete with their fathers), there is a quick clip of the space slug biting at their ship, as they are flying through asteroids.
One Family Guy episode has Peter shoo'ing Jawas away from his car, but I can't remember which one. The newest season's first episode also opened with a complete Star Wars throne room celebration recreation. There are also two scenes throughout the series where Ben is instructing Luke on the Force.
