Years ago, there was a film with Cary Grant, and
I think Robert Mitchum, I can´t remember the title. Anyway, they go
fly-fishing, and when one casts, the sound of a whining reel ratchet
is heard! I always thought it was the funniest part of the film!

There seem to be several such automatic errors.
E.g. aircraft rubber tyres normally squeak at touchdown
on a paved runway: and when aircraft touch down on
grass in movies (e.g. Battle of Britain) the sound track
usually supplies the tyre squeak (which does not happen
on grass.)
