The subplot about the hostility between Matthew and Joe is based on the real life relationship between Andy Dick and Joe Rogan. On the DVD commentary, the producers and writers discuss how one day Dick and Rogan would act like best friends, and the next they were constantly fighting.
Catherine: How'd your talk with Paul Simon go?
Jimmy: Oh, not so good. I think the world's going to have to wait for "A
Hazy Shade of White Walls".
Bill: (about his cane) Where is it?
Dave: I don't know. Maybe it took itself for a stroll.
Bill: We both know you took my cane. When you deny it, you insult not only
me, but yourself as well as...my cane.
Bill: (after Lisa effortlessly opens a glass Coke bottle) I'm assuming you dated a lot of frat guys.
Matthew: There's something not right between me and Joe. Every time he looks at me it's like he's zapping me with hate rays. It's like, zap zap zap zap.
Dave: Zap zap zap, huh?
Matthew: Please don't mock me, Dave.
Dave: Well, it's really hard not to.
Dave and Lisa kiss
Mr. James: No hanky panky on the desk. I've got cameras.
Mr. James: So what you're saying to me is that because of your personal relationship you see the value in noncompetitive cooperation?
Lisa and Dave: Yes.
Mr. James: Well that may work wonders in the bedroom but I tell you what, do me a favor and keep that kind of crap out of my office.
Mr. James quits the retreat early.
Mr. James: There's enough bad vibes in this room to run a hoodoo factory.
Lisa: Dave, what did you do in high school when you had a pop quiz?
Dave: Hyperventilated and got a note from the nurse.
Bill: Nice out there today. Perfect cane weather.
Dave: Well I guess Central Park must be full of idiots with canes then.
Bill: You know the old saying, everybody loves a cane.
Dave: No Bill, I think the saying is everybody loves a clown, which is what you look like with that thing.
Bill: I read your book, you magnificent bastard!
Having figured out Dave's cane hiding ploy, an exultant Bill quotes George C. Scott's performance as Patton in the Oscar winning movie of the same name (1970).
Matthew: I'm a little bit country...
While trying to get Joe to admit their differences, Matthew quotes a regular musical segment from the Donny and Marie show. By the way, Marie is the one who was a little bit country, Donny was a little bit rock and roll.
Jimmy: I guess the world's gonna have to wait for "a hazy shade of whitewalls."
Jimmy wants Paul Simon to endorse a line of tires. His proposed slogan is a parody of the Simon and Garfunkel song, A Hazy Shade Of Winter."
Mr. James: I've seen the coffee.... and the damage done.
Mr. James ask David if he needs more coffee, David replies no because he might have an overdose. Mr James says hes seen that happen and then says the quote to a bewildered David. It was undoubtedly a play on the words of Neil Young's 1972 song about the lethal results of heroin.
