Dan Frazer plays the hypnotist. He is best remembered for playing Captain Frank McNeil on Kojak (1973), which took place at Manhattan South.
In the opening scene, Barney is shown wearing the Bolo Tie he asked Harris to get him in Wyoming in The Architect (1980). Dr. Kramer asks Barney if he had forgotten where he put his real tie. It's not the last shot at Barney about the Bolo.
Wojo asks Harris if he thinks he should get hypnotized. Harris replies, "We could use the eggs." This is a reference to a joke told by Woody Allen in Annie Hall: "It reminds me of that old joke- you know, a guy walks into a psychiatrist's office and says, hey doc, my brother's crazy! He thinks he's a chicken. Then the doc says, why don't you turn him in? Then the guy says, I would but I need the eggs."
