 When Proctor is driving the bus, he narrowly avoids hitting a corner  fresh fruit stand as Harris yells, "Look out for Gene and Rogers  fruit stand!" This is a reference to movie critics  Gene Siskel (qv) and Roger Ebert (qv), who mentioned in a review  of one of the previous films that every Police Academy movie had to  feature stunt drivers crashing through rubbish bins or a fruit  stand. Despite the pair voicing their appreciation to the producers  for mentioning them in the movie, the film still received "two  thumbs down".
