Tommy Boy (1995)

Not-too-bright rich kid Tommy (Farley) teams up with snide, officious accountant Richard (Spade) to save the family auto parts business after dad (Dennehy) buys the farm. Tommy and Richard must deal with a conniving stepmom and stepbrother (Derek and Lowe), a ruthless rival (Aykroyd), and a road trip from hell to drum up some new business. Not as bad as it sounds, but inconsistent direction and too-familiar characters offset the amusing chemistry between Farley and Spade.
