How can Lt. Kraskow predict that they have "a body on the floor" due to the shot fired? One gunshot doesn't mean anyone has to be hurt, and everyone is actually lying down on the floor to begin with, as is common with hostage/robbery situations.
The first time we see Mulder's watch in this episode, the face is silver, but all the other times, the face is black, as it appears also in "Arcadia".
Mulder's waterbed is shown with a leak spraying water in the air. This might happen if one or more people were lying on the bed or pressing down on the mattress, but the fountain continues to spray when he is out of the bed. Waterbed leaks don't spray so much as ooze. Furthermore, the amount of water lost to cause the degree of saturation on the carpet (not to mention leaking into the apartment below) would mean that the bed would have lost most or all of its water, leaving Mulder waking up lying on the bottom of the mattress box.
Bernard: (Pointing gun at Scully) I'll shoot her!
Mulder: What do you think I'll do then?
Scully: Since when did you get a water bed?
Mulder: I-I might just as easily not have a water bed, and then I'd be on time for this meeting. You might just as easily have stayed in medicine, and not gone into the FBI, and then we would never have met, blah blah blah.
Mulder: Free will. With every choice, you change your fate.
Scully: Then let's change yours.
Mulder: So you think it's all just fate? We have no free will?
Scully: No, I think we're free to be the people that we are--good, bad or indifferent. I think it's our character that determines our fate.
Mulder: You can change your fate.
Robbery Note: This is a robbery.
Put the money in the bag.
Bernard: Why are you always in a mood?
Pam: 'Cause nothing ever changes.
Mulder: (repeating it to himself) He's got a bomb, he's got a bomb, he's got a bomb, he's got a bomb, ...
Pam: (to Mulder) Don't you see? We're all in hell. I'm the only one who knows it.
Mulder: Scully, did you ever have one of those days you wish you could rewind and start all over again from the beginning?
Scully: Yes, frequently. But, I mean, who's to say that if you did rewind it and start over again that it wouldn't end up exactly the same day?
Pam: (resigned, not looking at them as they run past) Go, go, go.
SWAT Team Leader: Go, go, go!
Bernard: Customers, face down! You know what this is!
Mulder: I know. I missed the meeting.
Scully: You didn't miss the meeting. You're extraordinarily late for the meeting. It's still going on.
Mulder: What are you doing down here?
Scully: We took a short break and I came looking for you. What are you doing down here, Mulder?
Mulder: (sarcastically) I'm having the best damn day of my life. Any moment I'm about to burst into song-- "Zip a dee doo dah." My, uh, waterbed sprung a leak and shorted out my alarm clock. My cell phone got wet and crapped out on me and the check I wrote my landlord to cover the, uh, damages is going to bounce if I don't deposit my pay. You ever have one of those days, Scully?
(Mulder crosses to the door.)
Scully: Since I've been working here? Yeah. When did you get a waterbed, Mulder?
(Mulder pauses in the doorway and thinks about it for a moment. Scully stares at him questioningly. Mulder ignores the question.)
Mulder: Bank's just down the street. I'll be back in ten. Cover for me, will you?
Scully: When do I not?
Scully's comment "when did you get a water bed?", refers back to 'Dreamland II', when Morris Fletcher bought himself a new water bed, thinking he would be living the rest of his life in Mulder's body.
The mirrors on the ceiling of the room were also put by Morris Fletcher.
According to writers John Shiban and Vince Gilligan, the inspiration for this episode didn't come from Bill Murray's 1993 comedy Groundhog Day, but from an episode of The Twilight Zone called 'Shadow Play.'
Writer Vince Gilligan gives us another reference to his girlfriend, Holly Rice. The Cradock Marine Bank is named for a suburb of Portsmouth, Virginia where Holly grew up, and Holly's mother's maiden name is Bernard.
Movie: Groundhog Day
In the movie "Groundhog Day", Bill Murray keeps experiencing the same day repeatedly. However, he is the only person who remembers the previous "days".
