Tonight I've been busy messing around with what may be Burger King's most disquieting internet promo yet. Sith Sense will consume at least twice as much of your time as the burger chain's confounding Subservient Chicken site. I'm willing to bet you'll waste somewhere between 10 minutes and 30 years of your life with it.

Sith Sense allows you to play 20 Questions with a Flash animation of Darth Vader. So far, Darth is shooting 3 for 5 from the ones I've pitted him against. The Lord o' the Sith managed to correctly guess "cow," "video game" and "ass" but struck out when it came to "beer" and "President of the United States of America." For the later two, the closest he came to the correct answers were "hot sauce" and "time machine."

Anyway, click here to give this thing a spin. Prepare to be confounded or at least slightly bewildered.
