You're lost in the desert, dehyrating and hallucinating from thirst. Suddenly three beings appear: a perfectly in-tune fretless bassist; a struggling, out-of-tune fretless bassist; and a 6-foot tall pink rabbit. Each of them tells you a different direction to go to reach safety. Which one do you believe? The struggling, out-of tune fretless bassist -- because the other two are obviously figments of your imagination.
