Harry Mudd mentions that he put two and two together and came up with five, which is a thought experiment brought up by Fyodor Dostoevski in his philosophical book, Notes From the Underground.
Harry: (watching sci-fi on TV) Look at that, it's totally bogus.
Harry: The very act of disassembling someone's atomic structure and then reassembling without even a receiver on the end?
Neil: Okay, point taken. You need a receiver but what it really does, it destroys the original and makes an exact copy on the other side, the receiving end.
Harry: Yeah, but according to Heisenberg the very act of scanning would disrupt the original, thus making an exact duplicate impossible.
Neil: The Einstein-Podolsky-Rosen effect allows for that. How else do you explain the physics team in Australia that took apart a laser beam and recreated it a meter away? That's right.
Harry: Am I right in assuming they don't teach Einstein-Podolsky-Rosen in high-school science?
Neil: Yeah, I'm a little ahead of my... (pause) You know, it's nice having somebody around that understands this stuff.
Neil: Oh, sorry about the bottom-feeder crack. (Neil called him that earlier)
Harry: Okay. You are what you eat.
(Chuck looks into the room)
Chuck: Would you two geniuses get off your fat butts and come here and give us a hand?
Harry: (entering the Taggart house with Chuck and Neil) Wow. The prototypical human household. You know, I've seen pictures, but I've never actually been inside one.
Chuck: If you're looking for typical, you got the wrong shack, bubba.
Harry: Wait a minute. This is the... don't tell me, the... the foyer? And... look, the living room! The heartbeat of the American family. From Ozzie Nelson to Ozzy Osbourne. Both wisdom and compassion are regularly dispensed here.
Neil: Okay, you definitely have the wrong house.
Harry: I think she's absorbed too much existentialist philosophy.
Chuck: We are now talking to a string of computer code that's got the blues 'cause she read too many French books?
Harry: Yeah, she is depressed; happens to everybody.
The actual title may be a reference to the 1955 Alfred Hitchcock film of the same name.
Harry Mudd, the name adopted by the sentient, is the name of the quintessential con-artist from the original Star Trek television series. His first appearance (of several) is in the classic episode "Mudd's Women".
"No matter where you go, there you are."
This quote, spoken to Chuck Taggert (Peter Weller) by Harry Mudd just before he dies was originally said by Peter Weller in the movie Buckaroo Banzai.
