Worst case scenario.

I once got 'The Worst Case Scenario' handbook as a birthday present. Read it back to back. I now know what to do if a crocodile swims up the waste pipe and appears in my bath. How to turn a shower curtain into an improvised parachute if my rip cord snaps. How to turn a parachute into a tent, and a tent into a coracle, and a coracle into a guitar tidy for parties.

But this comment floored me. What if we are ALL wrong?
