A completely batty approach.What I actually said:
"It's a matter of trusting the eyewitness's firsthand experience over the vague and adhoc possibility of some generic optical illusion or misperception."
The question of whether wegs' car actually turned into a turnip is not one to be decided on the basis of how much you trust Freddy, who filed the report about the putative incredible turnip transformation.
Your feelings about what a great guy Fred is are largely irrelevant to deciding whether Freddy is barking mad about the turnip thing or whether the Ghosts of Turnips past finally got their vengence on wegs' car.
