According to dialog, Blanche left Oscar to go to Reno two years before this episode.
Felix yearns to take a photograph for Lifestyle magazine, a fictional counterpart to Life magazine.
Oscar: (after Felix scrubs his phone numbers off the wall) Felix, that was not a mess. Those were my hot numbers!
Felix: This is no place to put 'em down.
Oscar: Well, some people have little black books. But you could lose little black books. I never thought I could lose a wall!
Oscar: Besides, if Felix was going to end it all, he'd leave a note, neatly typed and in three volumes. He leaves a note when he goes to empty the trash!
Oscar: (pulling a suit from Felix's closet) Alright, that proves it. You satisfied? Felix didn't commit suicide.
Roy: It's a black suit. What does that prove?
Oscar: Well, Felix always wears his black suit for formal functions -- like funerals, weddings and suicides.
Rudy: Unger, this is a fast-paced, happening world. There are [sic] no time for formalities. Why do you think advertising has accepted me in such a big way?
Felix: Because your father-in-law owns the agency.
Rudy: Yeah, but he knows his daughter married a today guy!
Oscar: When my ex-wife used to have to have too much to drink, she'd put on her ballet shoes and do "Swan Lake." How I used to pray for a real lake so she would fall in! And a hungry crocodile would come along...
Roy: "Looks like Wall Street after a ticker tape parade."
