You want the truth? You can’t handle the truth! Or, at a bare minimum, you’re not going to like the truth.
The Lens of Truth — the all-seeing, illusion-breaking, magical item from Zelda: Ocarina of Time and Majora’s Mask — has lips. Why. This creepy little adornment is impossible to unsee. You’ve seen the truth and now you forever carry that burden.
