"Ernest Goes to Africa"
"Another scene that sticks out in my mind as being completely ridiculous is the car chase scene in the African wilderness. Rene and Ernest have taken an ostrich farmer's truck and are being chased by the henchmen. Driving at about twenty miles per hour on a fairly straight road, both henchmen are shooting at Ernest, who is in the back of the ostrich farmer's truck. Ernest, on the other hand, is throwing ostrich eggs at the henchmen and their driver. The henchmen never hit Ernest once during the five minute chase, but Ernest is able to fend them off by hitting them and their driver in the face, making their car swerve off the road and explode in a giant column of smoke. I should also add that Ernest is slingshotting the eggs, two at a time, from a large bra."
