one guy always lies, and one guy always tells the truth. so if you ask, which way would the other guy say, then the liar would point to hell, and the truthful guy would anticipate this, and point the same way, so you would go the opposite way that they're telling you.
"You know, I'm sick of following my dreams man. I'm just gonna ask them where they're going, and hook up with them later."
