Pete the bug guy says it'll take three more days because he has to find the queen. Bedbugs are not hierarchical and have no queen.
When the exterminator wants to look at Doug's leg, he activates the lamp that is on top of his magnifying glasses. But as soon as he activates them, they go out again and he doesn't turn them on again.
When Doug is heating a Hot Pocket in the microwave, we get a shot taken from the point of view of the oven interior, but there's no sign in the door window of the protective grid that prevents microwave radiation from escaping.
(Doug and Carrie are at a bar late at night)
Mike: So, you guys must be having a wild night.
Carrie: Oh, yeah, you should've seen us an hour ago. We really raised the roof at Rite Aid.
Doug: So it's $1,100 [to get rid of the bed-bugs], right?
Pete: Oh, god, no, no... it's gonna be at least $2,500.
Doug: $2,500? I want you to kill them, I don't want you to send them to private school!
Pete: There are a lot of myths about bed bugs, but one thing's true: they're as disease-ridden as a one-eyed whore.
Pete: Sleep tight... I think you know the rest!
Spence: Let's play Trivial Pursuit for it.
Danny: No good: you know too many 'things.'
Carrie: Like your parents are so clean.
Doug: They are! You can eat off them.
Doug: Look at us: drinking, out all night. Really takes me back to my junior college days.
Carrie: All 12 of them?
