Party animal Tommy Callahan! (Chris Farley) is definitely a few cans short of a six-pack. But after seven years, Tommy's finally earned his diploma-and a cushy job at Callahan Auto Parts. Returning home, Tommy gets some more great news: his dad (Brian Dennehy) is marrying a real "10" (Bo Derek), and Tommy will get the stepbrother (Rob Lowe) he always wanted. Awesome! But as fast as you can say "Who killed the keg?," the family business starts tanking. Now Tommy's got to hit the road with his dad's right-hand man, a smug numbers-cruncher (David Spade). And what these two don't know about salesmanship could fill a book-and a riotously funny movie!
