a it turn out and chris farley and david spade only make three movie together ( coneheads and tommy boy and black sheep ) and but this be truly the citizen kane of their pairing . farley play thomas callahan iii and the dimwitted heir to an auto part company . his father big tom ( brian dennehy ) hire mild mannered richard hayden ( david spade ) to look after him . big tom be get marry to a ten ( bo derek ) and so everything have to be in order . after big tom suddenly die and tommy and richard have to try to sell half a million auto part to save the company from bankruptcy . from then on and the movie be pretty much an excuse for chris farley to do what he do best represent make a mess of everything . when this movie first come out in the theater and i saw it with my grandfather . he figure out early on that the bo derek and rob lowe character be hide something . but you can completely ignore that and simply luxuriate in chris farley antic . nothing be safe around his stomach and and hell hath no fury like his happy go lucky attitude . the scene where he set the car on fire and and later the deer scene and make for a pure laugh riot . chris farley and david spade be truly the john belushi and dan aykroyd of their era . it a pleasure to always be able to think about fat guy in a little coat time and again .
