While in the nightclub one of the employees at the bar slips a drug in Kelly Robinson's drink, while at the same moment Alexander Scott (Bill Cosby) is seen drugging someone else's drink.
While recovering from being drugged the previous night Kelly is required to pay a formal visit to Mr. Takata. We see Kelly preparing to walk to the house and he's uncharacteristically dressed in a suit with a vest, a formal hat, and carrying a closed umbrella. This is an obvious homage to the character John Steed, a British agent, from tv show The Avengers which began airing 5 years earlier in 1961.
