Fist Pump: When Mulder wants to prove his theory on the case, he carries out a very kitschy pink plastic flamingo and puts it up in the front yard. He looks around confidently and pumps his both fists, and says: "Bring it on!"
Guys Are Slobs: Mulder is a mild one, tossing his sweatshirt in the corner of the bedroom (& Scully throws it back at his face), and he leaves his shoes on the bed before Scully kicks him out of the room.
Potty Emergency: After spending hours watching his un-perfected mail box through the peep hole and drinking orange juice, Mulder briefly considers using the empty container, but opts for the actual bathroom instead, giving someone exactly enough time to fix the damage he'd done without being seen.
Stepford Suburbia: The community looks a little too perfect and something ugly hides there.
There Is Only One Bed: Mulder has some fun teasing Scully by suggesting that she get in bed with him, but it's still not treated like a big deal. He goes off to sleep elsewhere, presumably on the couch.
Tulpa: The Monster of the Week, when the president of the homeowners' association created one to enforce the neighborhood rules.
Uncanny Village: A seemingly peaceful American-dream community controlled by the Home Owner Association, represented mainly by President Gene Gogolak. They have strict rules and regulations about everything and observing them is enforced by death threat.
Undercover as Lovers: Mulder and Scully are assigned on a case and they work undercover as husband and wife.
