<P> Bernie arrives at the island before Larry and Richard and plans the murders with Paulie ( Don Calfa ) , the hitman , on the phone , unaware the conversation is being recorded on his answering machine . Bernie then plants cash and a fake confession note implicating Larry and Richard in the insurance fraud . Paulie arrives , killing Bernie with a drug overdose . When Larry and Richard arrive at Bernie 's house , they find Bernie 's body . Before they can call the police , guests arrive for a party that Bernie used to host every weekend . To Larry and Richard 's amazement , the guests are too engrossed in their partying to notice he is dead , with the dopey grin from the fatal injection and his sunglasses concealing his lifeless state . Fearing implication in Bernie 's death , and wanting to enjoy the luxury of the house for the weekend , Larry proposes he and Richard maintain the illusion that Bernie is still alive , a notion that Richard finds absurd . Only the arrival of Richard 's office crush , Gwen Saunders ( Catherine Mary Stewart ) , a summer intern for the company , convinces him to go along with Larry 's plan . </P>
