When flying inter-island (over the vast 75 mile gap between O'ahu and
Kaua'i) in the Cardinal I'll occaisionally pretend to lose my way when
it's a passenger I know well... causing them to start suggesting
alternate directions, which are always wrong.

Another one is that approaching any island when the relative humidity
is above 50% you see massive cloud buildups over the mountains (fair
weather cumulous, but with tops at about 9-11K), since the humidity is
so high a light haze will obscure the actual island and I'll gently
lead my passenger to believe that we need to fly through the massive
thunderstorm ahead of us.
