 Victor (Dom DeLuise (qv)) tells J.J. (Burt Reynolds (I) (qv))  that it is a good thing they have a doctor on board in case someone  gets "swamp fever". This is a reference to  _Smokey and the Bandit II (1980)_ (qv) where Dom played a doctor  Burt picks up. He was treating a patient for swamp fever.
