The big problem with "bouncing a signal off a star" is twofold. First, stars emit radio energy, but they're not what you'd call reflectors any more than a light bulb is a mirror. Second, while you can use a Laser to bounce a signal off a reflector placed on the Moon (about 1 light second away)...
Not to mention that, since the nearest antecedent of "him" is a cartoon character, you seem to be carrying on a two-sided argument with a fictional character. Quick, Watson, the needle! ;)
