 The argument between Eddie Valiant and Roger Rabbit in the bar  concerning Roger not wanting a drink is a remake of a classic  cartoon argument switch. This technique was used in the Bugs  Bunny/Daffy Duck/Elmer Fudd cartoons "Rabbit Fire" and "Rabbit  Seasoning." Bugs and Daffy would argue back and forth as to which  hunting season it is (Rabbit/Duck Season) Bugs would trick Daffy  into saying "Duck Season" by saying "Rabbit Season."
