During one of the driving interstitial the guitar riff plays the Bonanza theme and the transition to the next scene shows a burning map as in the title sequence. This sets up a gag where Harry has actually let the map catch fire.
In the final scene, when Harry insists that Mascha not stay in Rutherford, but take a job she says she was offered, he delivers his parody of Humphrey Bogart's famous line. Harry's version: "I could never live with myself if I held you back. If you didn't take it, you'd regret it. Maybe not today, maybe not tomorrow, maybe not ever. But you'll regret it."
