favourite props in movies/tv

couldn't find a thread on this so here it is!

what is your favourite prop from a movie or a tv show? it can be well made, well used in the story, or just cool looking!

Mine is probably the guitar from Electric Dragon 80.000v! It looks sick, a modified (or based on, i cant quite remember) jazz master, with sharp edges and a snakeskin pick-guard, it's hard for a guitar to look cooler. I also love the way it's used in the film, introduced as a way for the main character to channel his rage, its harsh sounds fill the soundtrack and help set the movie's incredible tone.
