The Blue Dahlia (1946)
Mentioned in dialogue.
The "gay family with monkey" routine is a strong reference to the homosexual family relationship between the three returning war veterans in "The Blue Dahlia," especially since Buzz acts much like a monkey at various times, and since George is a very silent but thoughtful person (aka Silent Bob). Johnny, meanwhile, runs around with various women getting himself in trouble (like Jay).
